How To Clean Grout in Tile Floor: Best and Easy Way

So, how do you clean grout in tile floors? Follow this simple technique for an easy way to clean grout in floor tiles.  

Scrub the Grout With Brush and Warm Water

The first step in how to get grout and tile clean is to brush it using warm water to loosen ingrained dirt.  

Mix Equal Amounts of Warm Water and Vinegar and Spray the Grout

Lifts ingrained dirt and grime from the grout. Do not use vinegar on unsealed grout.  

Spray With Vinegar After Applying a Baking Soda Paste

Apply a baking soda paste, spray with vinegar, and allow to foam. Scrub with a stiff-bristle brush and then rinse with plain water before wiping dry.  

Add Some Hydrogen Peroxide to the Mix

Hydrogen peroxide lifts stubborn stains safely on unsealed and sealed grout. Mix with baking soda to make an effective tile and grout cleaning paste.  

Allow Up to 15 Minutes for the Oxygen Bleach To Work

Oxygen bleach effectively cleans heavily stained grout. Always rinse with clean water and wipe dry to prevent the dirt from resettling into your grout lines.  

Use a Professional Grout Stain Remover To Get Rid of the Stains

Commercial grout stain removers effectively remove mold and mildew from grout lines. Brush gently and follow directions on the bottle to avoid damage.  

Clean the Most Stubborn Grout Stains With Steam

Another effective how-to-clean-grout-on-tile-floor method that works particularly well on heavily soiled surfaces requires using a steam mop. Popular brands include Bissell, Hoover, and Oreck.  

Use Chlorine Bleach on the Grout Sparingly

An important consideration when thinking about how to clean dirty grout in tile floors relates to chlorine bleach. Use this cleaner sparingly as it weakens and fades grout, causing cracking.
