How to Clean Grout
Cleaning grout can be a labor-intensive job. If your grout is sealed and cleaned on a regular basis, you won’t have to spend a lot of time scrubbing. Unsealed grout, on the other hand, is hard to clean since it absorbs moisture and stains.
If you’re ready to bring your floors to life, start with a thorough sweep of the room. If you’re cleaning a backsplash or shower, wipe down the tile and grout with a dry microfiber cloth. Then, put on protective gloves. (You’ll be on the floor for a long time, so wear comfy clothes that can get dirty.)
You’ll need a grout brush and grout cleaner. A grout brush with stiff bristles works best. Then, select a cleaner based on your needs.
Check the directions on your product for specific instructions. For most grout cleaners, you’ll spray or apply the solution to the grout, allow it to set for a few minutes, work it in with your brush, and rinse with water.
How to Prevent Grout from Staining
To keep your grout from staining, add a sealer. A sealer covers the grout with a protective surface, blocking it from water and stains.
Applying grout sealer is simple. After cleaning your floors, spread it with a brush, foam roller, sponge, or mop. Allow it to dry before walking on the tile.

Frequently Asked Questions (FAQ)FAQ
Can you clean grout lines with vinegar?
Vinegar is not a good cleaner for grout. It’s acidic, which can cause it to eat away at the grout lines rather than clean them. Plus, it doesn’t do as good of a job cleaning as a homemade baking soda and hydrogen peroxide cleaner.
What’s the best shower grout cleaner?
For the shower, look for a gel or paste grout cleaner that clings rather than runs off. ZEP Industrial Grout Cleaner and The Pink Stuff Miracle Paste are two good options. You can also make DIY shower grout cleaner by combining peroxide, baking soda, and dish soap.
What to do if your white grout won’t come clean?
If you’ve scrubbed your grout with no luck, consider using a grout touch-up pen. These pens contain paint for grout lines, restoring them to their original color. They are easy to use and come in many colors, including white.
What’s the best everyday cleaner for tile and grout?
If you want to clean your tile and grout simultaneously, consider Rejuvenate Tile and Grout cleaner. You can spray it on your floor and mop. Since it’s enzymatic, it will keep working even after you clean.
How do I clean mold on shower grout?
The acidity in white distilled vinegar kills mold and mold spores, preventing them from growing back. But vinegar doesn’t do a great job of removing stains. So, after killing the mold, rinse well, and use a product like RMR-86 Mold Stain Remover. (Never mix vinegar with another cleaner, it can create lethal gasses.)
Nothing makes a room look dingier than dirty grout. And since grout is a pain to clean, you need a product that works. The products on this list will remove built-up dirt and many stains. Make sure you choose the cleaner that’s safe for your tile and fits your specific needs.
If you want to make your own grout cleaner, a mixture of baking soda, peroxide, and dish soap works wonders. You can also opt for a simple baking soda paste.
