Buying guide for Best grout cleaners

When it comes to household chores, cleaning the bathroom is rarely anyone’s favorite task. As unpleasant as scrubbing the toilet and shower can be, tackling dirty grout often creates quite the headache. A good grout cleaner can get the job done with less hassle.

Not all grout cleaners are the same, however. If you want an effective option for your tile surfaces, you have to determine the right formula, match your grout color and tile type to a compatible product, consider how it’s applied and how long you have to wait for the cleaner to work, and make sure that it fits your cleaning routine.

To keep your grout and tile surfaces as clean as possible, apply a grout sealant product 24 hours after using a grout cleaner.

What is grout?

Not exactly sure what grout is? It’s a mortar or paste placed between tiles in a floor, shower, or backsplash to fill in the gaps and hold the tiles in place. Grout has a porous, textured finish, which means it’s a magnet for dirt, mold, mildew, and other grime. It also easily absorbs liquids, so it’s very common for grout to take on a dingy, discolored look over time.

When it comes to tile floors, dirt either from outside or from mop water is the most common culprit behind dirty grout. In the shower, mold and mildew are usually the reason grout becomes dingy. While in the kitchen, food and cooking residue is the most likely source.

Expert Tip
Be very careful when using grout cleaner. Don't allow it to sit or spill on unsafe surfaces.

How to use grout cleaners

The best way to use a grout cleaner depends on the formula, so always consult the manufacturer’s instructions before cleaning grout. In general, though, you should start by washing the tiles with a mixture of warm water and mild dish soap. For a tile floor, sweep or vacuum, and then mop or use a grout steamer. Once the tile surface is clean, apply the grout cleaner to the dirty grout. Allow the formula to sit on the grout for the time specified on the bottle. After the appropriate amount of time, wipe the cleaner away, rinse the area with warm water, and dry the grout with a clean towel. For a deeper clean, use a scrub brush to wipe away the grout cleaner.

Features to consider for grout cleaners


Grout cleaners often contain very potent ingredients like bleach, so it’s important to choose a formula that’s as safe as possible, particularly if you have children or pets at home. Look for an acid-free, non-toxic grout cleaner that won’t pose a risk to kids or animals. It’s also a good idea to choose a fume-free formula so that you don’t need to wear a mask when you use it.

Grout cleaners that contain oxygen bleach are often the best option. For the safest results, choose an oxygen bleach-based cleaner that’s organic, that’s fragrance- and dye-free, and that contains FDA-approved food-grade-quality ingredients.

Grout color

Some grout cleaners aren’t suitable for use on all colors of grout. In particular, oxygen bleach-based formulas can sometimes discolor colored grout. Most cleaners do work for white or light-colored grout, but if your grout is a dark shade like tan, brown, gray, or black, always check the label to make sure that the cleaner is compatible with your grout color.

There are also some grout cleaners that are designed for specific grout colors. For example, you could use a white cleaner for white grout or a chocolate cleaner for brown grout. These formulas not only clean the grout but leave a tint of color behind to refresh the grout’s appearance. If you opt for this type of formula, it’s extremely important to get the color right.

Tile surfaces

When you’re cleaning grout, it’s inevitable that some of the grout cleaner will get on the surrounding surfaces. That’s why it’s important to make sure that the formula you choose is safe for the surfaces in your home.

Most grout cleaners are safe for ceramic and porcelain tile, but some aren’t suitable for use on natural stone tiles like marble, slate, or granite. Always check the product specifications to make sure that you can use the grout cleaner that you’re considering on your tile surfaces.


Grout cleaners are available in several different types of containers, but the most common are spray bottles, squeeze bottles, and pour bottles.

A container with a spray nozzle is usually the best option for a grout cleaner. It allows you to concentrate the product along the grout line so you don’t get it all over the floor, wall, countertop, or any other surface. The cleaner usually comes out in a fine spray, too, which prevents you from applying too much.

Squeeze bottles often have a nozzle as well, but it’s usually more difficult to control how much of the cleaner you apply. Pour bottles are typically oversized containers, and the cleaner is meant to be transferred into a smaller spray or squeeze bottle. If you try to apply grout cleaner directly from a pour bottle, it’s impossible to control how much you apply or where you apply it.

Buy the correct amount of solution for the job so you won't need to make repeat visits to the store to purchase more products.

Time required

A grout cleaner usually needs to sit on the grout for a certain amount of time in order to fully penetrate the grout, kill mold and mildew, and remove stains. Some cleaners only require 10 minutes, while others may require up to 24 hours. You’ll need to stay off the floor or keep items off other surfaces that you’re cleaning while you wait for the cleaner to work, so fast-acting formulas are considerably more convenient.

Check the manufacturer’s instructions for the recommended time required for the grout cleaner to work to make sure that it will fit your cleaning schedule.

For your safety
Even if you’re using a non-toxic product, it’s a good idea to wear safety goggles and gloves while applying a grout cleaner.

Tinted grout cleaner and refresher products that leave a color behind typically range from $15 to $20.


Oxygen bleach-based grout cleaners that can be used on most grout colors and tile surfaces usually cost between $20 and $42.

Expert Tip
Read the back of each product. Sometimes the trick isn’t how much product you put down or what you scrub with, but how long you need to let the cleaning solution sit on the grout before scrubbing.
BestReviews Cleaning Expert


  • Even if you choose a fume-free grout cleaner, open a window or turn on a fan in the room that you’re cleaning to make sure you have proper ventilation.

  • It is important to read the back of each product. Sometimes the trick isn’t how much product is put down or what is used to scrub it but also how long you are to allow the cleaning solution to sit on the grout prior to scrubbing.

  • After the grout cleaner has soaked into the grout, you can use a brush to scrub the product into the grout to remove really stubborn stains.

  • Once you’ve let the grout cleaner sit on the grout for the specified time, always rinse it away with clean water. If you don’t, the grout can sometimes reabsorb the dirt and grime trapped in the cleaner.

  • To remove any grout cleaner residue that might be left behind on tile floor, mop the floor after you’ve rinsed away the product. Use a solution of warm water and a small amount of gentle dish detergent.

If your grout is severely stained, a grout cleaner may be unable to remove all the discoloration. In that case, the grout may need to be replaced.


Q. How often should I use grout cleaner?

A. It depends on how well you maintain the grout and the conditions it’s exposed to. In general, you should use a grout cleaner whenever you notice the grout starting to look dark and dingy. That usually means doing a deep-cleaning of the grout once or twice a year.

Q. Does a grout cleaner remove grout sealant?

A. Some grout cleaners will strip away any sealant product that you’ve applied on top of the grout. If you want to preserve your sealant, opt for a gentle formula that’s acid-free and has a neutral pH.

Q. Can I use grout cleaner on tile walls?

A. You can use grout cleaner on tile walls, but you may want to adjust your cleaning technique slightly. Grout cleaners are usually fairly liquid, so they’ll run if you apply them on a vertical surface like a wall. Instead of applying the cleaner directly from the bottle, you may want to dampen a scrub brush with the product, and then run the brush along the grout on your walls to concentrate the cleaner in the right areas.
