7 Best Tile Grout Cleaners of 2024, Tested by Experts – Good Housekeeping

Grout material and color: Read the label before buying any grout cleaner to be sure it is safe to use on the surfaces you'll be cleaning. Some are suited only for white, not colored, grout, and others can damage adjoining tiles made of natural stone, like marble or granite.

Cleanser form: Sprays and foams are easy to apply but can run or drip off vertical surfaces before the job is done, meaning you may have to reapply. And some may produce fumes that can be irritating, especially when used in small spaces. Thick gels stay in place longer, but they can take more effort to rinse away.

Scope of the job: Bleach is a great whitener and germ-killer, so if your grout is very badly stained with mold and mildew, a strong bleach-containing cleaner will be your best bet and will likely require the least amount of scrubbing. If you'll be cleaning dirty or discolored floor tile grout or you're fastidious about drying the shower daily and have only occasional spots, a milder formula should suffice.
