The 9 Best Grout Cleaners for 2023

The 9 Best Grout Cleaners for 2023

Grout cleaners are cleaning products designed to remove dirt, grime, and stains from grout, the porous material between tiles. Over time, grout can become discolored and stained, particularly in areas with high foot traffic or exposure to moisture.

There are many types of grout cleaners available, including acidic, alkaline, oxygenated, enzymatic, and steam cleaners. Acidic cleaners are effective at removing mineral-based stains like rust and hard water deposits, but can be harsh on some surfaces. Alkaline cleaners are less harsh and work well on most surfaces. Oxygenated cleaners are a good all-purpose cleaner that are effective and safe to use. Enzymatic cleaners are a good choice for organic stains like mold and mildew. Steam cleaners are a good choice if you want a chemical-free option.

Grout isn’t something we usually notice until it becomes grimy, dark, or dingy. However, with the right cleaner, it’s easy to restore grout—and the surrounding tile—to its original beauty. Following application, grout lines can become smoother, brighter, and cleaner. But with so many kinds available, choosing the right grout cleaner can be tough. In order to help make the decision easier, we tested several types of grout cleaners to see which ones worked best and actually stood up to the claims they made to deliver a sparkling-clean result.

The 9 Best Grout Cleaners for 2023:Tested and Reviewed

Keeping your grout clean is a fantastic way to have a sparkling kitchen and bathroom, whether your grout is colored or neutral to match the rest of your home’s decor. But to have sparkling spaces, you need to have the right and most effective cleaning tools and products in your cabinets. After researching and testing, we determined the best grout cleaners are easy to apply and work on a variety of stains and messes.Since grout is porous, it can collect dirt, water stains, mold, and mildew. If you want to cut down on scrubbing, choose a product that does the heavy cleaning for you.

#1.Soft Scrub Soft Scrub Gel Cleanser with Bleach

Soft Scrub

The Soft Scrub with Bleach Cleaner Gel was our favorite cleaner by far when testing.
Value for money


Application: Squeeze-on gel
Meant for: Safe for all surfaces, although prolonged contact with metal, old porcelain, or plastic countertops may cause discoloration
Special features: Dye-free, made in the USA



  • Whitens highly effectively
  • No scrubbing needed
  • Pleasant smell


  • Will stain clothing very easily
  • Contains bleach
  • May not be safe for all surfaces

Not only did it work incredibly quickly and easily on all of the filthy grout surfaces in our house—including a kitchen, bathroom, and mudroom that five children, two adults, and one farm dog use—it also can clean pretty much anything in the house, including countertops, tubs, showers, sinks, stovetops, tiles, and toilets.

It contains bleach, so it will clean everything from mold to mildew to limescale stains to plain old grime. It made our grout whiter and cleaner than any other cleaner, and the difference was drastic. The only warning to be aware of when using Soft Scrub with Bleach is that it will stain dark clothing, so be sure to dress accordingly or wear protective gear when cleaning. Additionally, using bleach frequently on grout can damage it over time, so use this cleaner sparingly, and be sure to follow all recommended instructions, and do not let it sit for longer than the recommended 1 minute of soaking time.

#2.Grout-Eez Super Heavy-Duty Grout Cleaner


This heavy-duty grout cleaner can return your grout to a sparkling clean even if it has been stained for years, which is why it’s our top pick.
Value for money


Price at time of publish: $22 | Type: Spray | Amount: 32 fluid ounces | Safe for Use On: Ceramic, porcelain, and grout



  • Very effective and cleans quickly
  • Safe for any color grout
  • Safe for porcelain and ceramic
  • Scrub brush included


  • Strong smell
  • Not safe for natural stone

It picks up grease and grime, two things that can be common culprits in the kitchen and on tile floors. The formula works on tile and grout, including porcelain and ceramic too. All you need to do is spray it on, let it sit for around five minutes, and scrub.

Depending on the amount of dirt and grime, the cleaning task may take some scrubbing or be as simple as wiping the cleaner away. Our tester noted that the nozzle design is not the most helpful for cleaning grout on walls, as well, but loved the results. “Because there is a substantial amount of surface area in our shower, we can’t say that our arms didn’t fatigue with scrubbing,” she said. “But after just one pass, all of the rust-colored stains were easily lifted, and the tiles looked almost like they did when we first moved in.”

Notably, the formula works on both white grout and colorized grout. While it works on most surfaces, it isn’t safe for natural stone. Because it comes in a spray bottle, you can use it on the grout lines of natural stone tile and aim for those specific areas. It has a slightly strong scent as well, which you will likely pick up on quickly—our tester noted that it was pretty powerful. While not totally unpleasant, anyone sensitive to chemical-based scents may find the cleaner’s scent is too powerful.Ultimately, whether you are cleaning in a small, enclosed area, such as a bathroom or shower, or a large one, it’s best to ventilate while using this cleaner and follow the safety guidelines that are noted on the packaging. Crack open a window and wear protective eye gear and gloves, so the cleaner doesn’t come in contact with your eyes or skin.

The Grout-Eez grout cleaner does use some harsher chemicals than the eco-friendly alternatives. For that reason, it may not be the best choice for food prep areas, such as kitchen countertops. It is ideal for backsplashes behind the stove or entryway floors that see a lot of mud and dirt. The included scrub brush can attach to any standard-sized mop or broom for use on the floor and larger areas, as well, and is angled to get into corners and grout lines.

#3.CLR Brilliant Bath Foaming Bathroom Cleaner Spray


CLR Brilliant Bath Foaming Bathroom Cleaner Spray
Our cleaning experts are fans of CLR’s bathroom products.
Value for money


Type:Foaming spray
Safe for use on:White grout, plastic, glass, chrome, ceramic, fiberglass, porcelain, sealed granite and stainless steel
Wait time:2 to 3 minutes

  • EPA Safer Choice Certified
  • Works with minimal scrubbing


  • Recommended only for white grout

They swear by this foaming bathroom cleaner so much, they’ve included it in our list of the best shower cleaners and bathroom cleaners and have featured it in a guide for removing stubborn hard water stains. Unlike some others we’ve tested, this cleaner needs to sit on a surface for only two to three minutes to work its magic. It works on surfaces all around the bathroom including the toilet, sink faucets and bathtub. And while it’s great at removing stains from white grout, the manufacturer does not recommend using it on colored grout to avoid removing the hue. It’s EPA Safer Choice Certified, too, so that means every ingredient in the formula has been evaluated by the EPA and deemed safer for consumers and the environment than others with harsher ingredients.

#4.Ultimate Grout Cleaner for Tile Floors Blasts Away Years

#5.Seventh Generation Seventh Gen

Seventh Generatio

Seventh Generation Seventh Gen
As an all-purpose cleaner, this eco-friendly pick can be used to clean both grout and surfaces in the kitchen and bathroom.
Value for money


Application: Pour-on
Meant for: Acrylic, ceramic, fiberglass, porcelain, satin, nickel, stainless steel; not for use on marble or glass
Special features: Septic safe, biodegradable, USDA Certified Biobased Product, nontoxic



  • Nontoxic
  • Pleasant smell
  • Biodegradable


  • Very large refill bottle
  • Won’t whiten grout
  • Does not remove mold or mildew

It may not whiten and brighten as well as more harsh cleaners, but we do like the idea of a more gentle, nontoxic cleaner for the tub that toddlers and children will use for bathing. Just keep in mind it’s not the most effective cleaner for removing tough stains or a lot of mold and mildew, but for everyday cleaning or simple dirt and soap scum, it gets the job done.

This cleaner is a way to both prevent and cure in one concentrated solution. Its eco-friendly liquid is formulated with citric acid, plant-based ingredients, and essential oils—without chlorine bleach, artificial fragrances, dyes, or solvents. Instead, the main ingredients in this cleaner are water, citric acid, caprylyl/myristyl glucoside (a plant-derived cleaning agent), abies balsamea (balsam fir) extract, citrus aurantifolia (lime) oil, and cupressus sempervirens (cypress) oil.

It is safe for use on a range of surfaces, including ceramic tile, shower doors, plastic, chrome, fiberglass, porcelain, stainless steel, and more (it’s not advised for marble or brass, though).While this tub and tile cleaner doesn’t include fake fragrances, it is scented quite heavily with essential oils, so people with sensitivity to smells should take note. Additionally, it might be helpful to decant into a spray bottle, as the product is sold as a pourable bottle only.

#6.Goo Gone Grout & Tile Cleaner

Goo Gone

Goo Gone Grout & Tile Cleaner
This affordable grout cleaner works on so many surfaces that it’s a no-brainer to include it in your cleaning arsenal.
Value for money


Price at time of publish: $11|Type: Spray | Amount: 28 fluid ounces | Safe for Use On: Grout, ceramic, porcelain, fiberglass, and natural stone



  • Safer ingredients
  • Works on a variety of surfaces
  • Cleans mold and mildew stains


  • Not for marble, limestone, or travertine
  • Contains chemical fragrance

While it isn’t as effective in every situation as a professional-strength option, the chemicals are less harsh. You can use it on grout, ceramic, porcelain, fiberglass, and natural stone. It is also safe for white and colorized grout. The only surfaces you should not use Goo Gone cleaner on are limestone, travertine, and marble.

The grout cleaner cleans up mold and mildew stains, as well as common dirt and grime from things like soap scum, hard water, and shampoo. The formula is also certified as a safer choice for your health and the environment by the U.S. Environmental Protection Agency (EPA). Benzenesulfonic acid sodium salts and alcohol are the two main cleaning agents. It also includes chemical fragrance, which you should absolutely keep in mind if you are sensitive to fragrances.

#7.Better Life Natural Tub and Tile Cleaner

Better Life

Better Life Natural Tub and Tile Cleaner
Finding an effective, eco-friendly cleaner for bathroom tile and grout can be tricky.
Value for money


Price at time of publish: $14| Type: Spray | Amount: 28.6 fluid ounces | Safe for Use On: Porcelain, ceramic, grout, stainless steel, fiberglass, acrylic, and chrome



  • Safe for many surfaces
  • Uses all-natural ingredients
  • Scent from essential oils


  • Requires more scrubbing
  • Can’t use on brass, wood, marble, granite

But, this Better Life option uses safe ingredients, including coconut, corn, and citrus-based cleaners, as well as essential oils for fragrance. The formula does not include alcohol, petroleum-based solvents, synthetic fragrances, dyes, chlorine, or bleach. If you have kids and pets in your home, this is an ideal choice.

The only downside? Expect to do a bit more scrubbing with this formula. Fortunately, it is safe to use on porcelain, ceramic, grout, stainless steel, fiberglass, acrylic, and chrome. That means you can use the same cleaner on most of your bathroom and kitchen fixtures, as well as the tile and grout. Just steer clear of brass, granite, marble, and wood.

#8.Granite Gold Grout Cleaner Spray

Granite Gold

Granite Gold Grout Cleaner Spray
Grout cleaners are not all suited to clean every type of grout.
Value for money


Safe for use on:Stone, ceramic, glass and colored grout
Wait time:2 to 3 minutes



  • Safe to use on natural stone
  • Works on white and colored grout


  • May not be as effective on very dirty grout

In fact, most traditional bathroom and grout cleaners cannot be used to clean stone surfaces like marble or granite. This cleaner from Granite Gold cleans stone grout without the chemicals (ammonia and acid) found in traditional cleaners that could etch the natural stone. It comes with a brush to work the formula into the grout without causing damage, but the formula might not be effective on very dirty grout because of its milder ingredients.

#9.Zep Grout Cleaner and Brightener

Zep Grout

Zep Grout Cleaner and Brightener
If you want to give your white grout a pick-me-up, the ZEP grout cleaner and brightener is a great option.
Value for money


Price at time of publish: $31|Type: Liquid | Amount: 32 fluid ounces | Safe for Use On: Grout, ceramic, and porcelain



  • Brightens as well as cleans
  • Safe for white or colorized grout
  • Easy to apply
  • Acid lifts stains quickly


  • Strong chemicals
  • Not good for many surfaces
  • Liquid can spread

You can pour the liquid right on the grout and scrub to get it into the stains. Then, rinse or wipe away. ZEP recommends resealing your grout after use since the cleaner can eat away at the previous sealant. Resealing also helps the brightening last longer.

Now, the cleaner does use acid to lift stains and clean, so it’s best to test it on a small area to make sure it won’t scratch or discolor your grout or tile. It is safe for colorized grout but may not be the best choice for all surfaces, especially natural stone. Marble, terrazzo, travertine, natural stone, chrome, stainless steel, brass, and Corian can all be damaged easily. If you do use this cleaner on grout near these surfaces, make sure to tape off the areas you do not want to be touched with a tape that seals well since the liquid formula can spread.

How we test tile grout cleaners

When the YeaPei experts test bathroom cleaning products, we test them in the lab and bring them home to test on our own soap scum, mildew and hard water stains. In the Cleaning Lab, we assess how easily and quickly they cut through the dirty grout lines on our ceramic and marble tile test panels. We note the wait times and how much scrubbing is required for each cleaner to work. We review the labeling and directions for completeness and for any required safety precautions, and we evaluate how easy the products are to apply and rinse off.

Products that are submitted for consideration in our annual Cleaning and Organizing Award are shipped to our team of consumer testers to clean and assess the performance on the soap scum and mildew-stained grout in their own showers, which you just can’t duplicate in a lab.

Key Considerations for Choosing the Best Grout Cleaner

Grout cleaner should be gentle enough to polish tile without scratching it but strong enough to eliminate grout discoloration due to mold, mildew, and dirt. Whether cleaning a floor, kitchen backsplash, or shower stall, the best results can depend on the following factors:

Active Ingredients

To be effective, grout cleaners lift dirt, erase mold, clean soap scum, and brighten tile with ease. Choose a product based on the desired result.

Mold and Mildew Removal

Depending on the severity of the mold situation, a grout cleaner with one of the following ingredients may be desired: an acid, hydrogen peroxide, oxygen bleach, or chlorine bleach.

  • A mild acid-based cleaner (containing citric or oxalic acid, for example) is the least harsh of these formulas and typically won’t damage chrome, stainless steel, or tile.
  • An oxygen bleach (containing hydrogen peroxide) is moderately strong, while chlorine bleach is the strongest and most caustic.
  • Chlorine bleach formulas should only be used when the goal is to whiten, as they can also lift color from dyed grout.

All of these ingredients will also kill germs and bacteria, which, when applied in low doses, can be helpful, especially in bathroom and kitchen areas.

Whitening and Brightening

While chlorine bleach is often a go-to ingredient in whitening products, it is not necessarily the best or only option. Bleach is associated with health concerns (respiratory damage, for example), and it can also release harmful airborne particles when mixed with other cleaning substances. That said, it can have a place in a cleaning regimen if used in small doses.

Beyond bleach, citric and oxalic acid can also lift soap scum and surface staining. The right abrasive product can really get the dirt out, restoring grout and tile to an almost-new appearance. Look for products containing feldspar. This naturally occurring mineral is crushed into a fine powder, which works wonders on hard surfaces, including grout and tile.

Grout Color

It’s important to make sure a grout cleaner is appropriate for the grout color. Not all grout cleaners are intended to clean colored grout. Some, like those that contain bleach, are designed to only whiten and brighten white grout lines.

While bleach and other harsh cleaners can be effective for cleaning white grout lines, they can also break down the grout over time and eventually cause damage that will allow mold to grow. Additionally, breaking down the grout can lead to even more discoloration. If there are colored grout lines, be sure the grout cleaner is safe for colored grout.Grout is porous, so it will absorb any cleaner used on it, and using the wrong cleaner could damage the grout lines.

ile Material

Not all grout cleaners can be used on all types of tile material. The more porous the tile material, the more likely it is that the wrong grout cleaner could damage the tile or cause discoloration. Some materials are more porous than others. For instance, sandstone is very porous, while granite is not very porous.

One of the common warnings regarding grout cleaners are for natural stone surfaces, which are susceptible to discoloration. Check the label for a list of what type of materials the grout cleaner can and cannot be used on.

If unsure about the tile material, test the tile by putting a drop of water on it. If the water absorbs and leaves a “wet” mark, it’s likely very porous. If the water sits on the tile and doesn’t absorb, it is nonporous. Use additional caution when working with porous tile.

Cleaning Time

Most grout cleaners will need to be applied and allowed to sit for several minutes before scrubbing in order to be the most effective. And some strong cleaners come with a clear warning to not let the cleaner sit more than the allotted time. In fact, letting the cleaner sit longer than the recommended time could actually damage the grout and/or the tile. For instance, abrasive cleaners that contain bleach or other acid-based cleaners can cause damage to the grout over time.

Additionally, using harsh scrubbing action with abrasive cleaners can cause holes and break down the grout, which can lead to discoloration. If there are any holes and breakdowns, the grout will need to be repaired.

Application Method

There are two ways to apply grout cleaner: (1) spray and wipe, or (2) scour with a brush. Spray-on products claim to work without scrubbing, which can save time and energy. On the downside, these cleaners may contain harsher acids, solvents, or chlorine bleach. Therefore, it’s important to weigh the benefits of elbow grease saved with the toxins released into the home environment.

Scouring with a brush and cleaner does require a little work, but this method can be especially effective on floors and heavily soiled grout. For tools, a toothbrush can be used on small grout lines. A brush or scrub pad is best for floors and backsplashes. Some brands provide both the liquid cleaner and a scrubbing tool or broom head. To prevent scratching the surrounding tile, use gentle pressure and avoid overly vigorous scrubbing.

Health and Surface Safety

A variety of harsh chemicals can be found in some commercial grout cleaners, with bleach and ammonia often playing a key role. These active ingredients can be efficient at scouring away surface stains, soap scum, and mold, but they can also affect the user’s health adversely as well as harm the environment.

  • Chlorine bleach and ammonia can be caustic and poisonous if improperly used. Both chemicals can cause skin and eye irritation as well as respiratory damage. At the same time, their whitening powers are almost unbeatable, especially where tough grout stains, mold, and mildew are concerned.
  • High levels of phosphates have been linked to irritation in humans, as well as having an impact on water systems and aquatic life. However, they are also useful in softening water, cutting through soap scum, and improving cleaning products’ efficiency. Since the 1960s, the U.S. has been increasing regulation on phosphates, which has removed this additive from many cleaning products and detergents, though not all. This is why “phosphate-free” still appears on the label of some grout cleaners.

Before ramping up product strength and turning to bleach or man-made chemicals, consider trying a healthier, plant-based option first. They are still effective in most situations. Look for products with the Environmental Protection Agency (EPA)’s Safer Choice seal as well as a list of active ingredients. If the brand does not disclose all its ingredients on the label, search the Environmental Working Group’s Guide to Healthy Cleaning. This database provides independent research on product toxicity and safety.

For our recommendations, we’ve prioritized the safest options on the market today. The two exceptions are bleach and industrial-strength grout cleaner, which are still useful in certain circumstances. Any formulas labeled heavy-duty or containing these chemicals require careful handling and protective gear: rubber gloves, face mask, goggles, and good ventilation.

Most grout cleaners will also coat surrounding surfaces, so make sure the product is formulated for safe contact with those materials. Always double-check the label, as most grout cleaners list the surfaces they are designed for. In the case of granite, marble, and unsealed natural stone, look for cleaners designated safe for these materials.

Before spreading grout cleaner over an entire backsplash or tiled surface, spot-test it on a small, unnoticeable area. This is especially important for industrial-strength cleaners.

Grout Cleaner Types

There are several types of grout cleaners available in the market, and the most common ones are:

  • Acidic Grout Cleaner: These cleaners are formulated with acidic chemicals such as hydrochloric acid or phosphoric acid to break down stubborn stains and grime in the grout. They are highly effective but can be harsh on some surfaces and can also emit fumes that are harmful to inhale.
  • Alkaline Grout Cleaner: These cleaners are formulated with alkaline chemicals like ammonia or sodium hydroxide to dissolve and remove dirt and stains from the grout. They are less harsh than acidic cleaners and work well on most surfaces.
  • Oxygenated Grout Cleaner: These cleaners use oxygenated bleach as their active ingredient, which is less harsh than acid or alkaline cleaners. They are effective at removing stains and can be used on a wide range of surfaces.
  • Enzymatic Grout Cleaner: These cleaners use enzymes to break down dirt and stains in the grout. They are non-toxic and environmentally friendly, making them a good choice for households with pets or small children.
  • Steam Grout Cleaner: These cleaners use hot steam to remove dirt and grime from grout. They are effective and environmentally friendly, as they don’t require any chemicals, but they can be more time-consuming than other types of cleaners.

It’s important to choose a grout cleaner that is suitable for your specific needs and the type of grout you have. Always read the label and follow the instructions carefully to ensure safe and effective use.

Grout Cleanersr pros and cons

Buying Grout Cleaners FAQs

Is bleach bad for grout?

Using bleach frequently to clean grout can eventually damage the grout’s structure, so use it sparingly. Additionally, there is a risk of damaging or discoloring nearby surfaces, so bleach-based cleaners should be used carefully.[1]Is Bleach Bad for Grout?

How do you clean really dirty grout?

Choose a cleaner tailored to the type of debris that is being removed. Mold and mildew, for instance, may require a different cleaning agent than simple dirt does.[2]How To Clean Tile And Grout

Is it important to seal grout lines?

It can be helpful to seal grout lines at least once a year to help protect them and prevent staining.

How often should tile and grout be cleaned?

At the least, it’s recommended that grout and tile are cleaned every 6 months, but some tile and grout may need cleaning more frequently in high-traffic areas or areas prone to mold and mildew growth, like showers.[3]How often should I have my tile and grout cleaned?

How can you make your grout white again?

Any professional strength cleaner will be effective at lifting stains and making your grout white again. White vinegar is a great all-natural option to clean grout. However, make sure that your grout is sealed or it may become damaged. If your grout is very worn or stained, you may want to replace sections. Sealing it can help your grout stay white longer with regular cleaning.

How do you make your grout cleaner?

Sealing is the best way to protect your grout and keep it clean. After you thoroughly clean the grout, seal it right away. This helps protect the grout and makes it harder for dirt and grime to build up and stain the grout. You will still need to regularly clean the grout, but it should be easier and faster.

How can you tell if grout is sealed?

The easiest way to test if your grout is sealed is to pour a small amount of water on it and observe closely. If the water beads up, the grout is sealed. If the water penetrates the grout, usually observed by the grout darkening in color, it is not sealed. It is possible for sealed grout to wear over time and no longer provide the same layer of protection. In this case, it will look like unsealed grout and need to be resealed.[4]Indicators to tell if your grout is sealed

What type of grout cleaner should I buy?

Acidic cleaners are very effective at removing tough mineral-based stains, but can be harsh on some surfaces. Alkaline cleaners are less harsh and work well on most surfaces. Oxygenated cleaners are a good all-purpose cleaner that are effective and safe to use. Enzymatic cleaners are a good choice for organic stains like mold and mildew. Steam cleaners are a good choice if you want a chemical-free option.

Are all grout cleaners safe to use on all surfaces?

No, not all grout cleaners are safe to use on all surfaces. Acidic cleaners can be harsh on some surfaces, particularly natural stone and polished surfaces. It’s important to read the label carefully and make sure the cleaner is safe to use on your specific type of surface.

Can grout cleaners be used on colored grout?

Some grout cleaners can be used on colored grout, but others may cause discoloration. It’s important to read the label carefully and make sure the cleaner is safe to use on colored grout.

Can grout cleaners be used on all types of tile?

Most grout cleaners can be used on ceramic and porcelain tiles, but not all cleaners are safe to use on natural stone or other types of sensitive surfaces. It’s important to read the label carefully and make sure the cleaner is safe to use on your specific type of tile.

How do I know if a grout cleaner is environmentally friendly?
