Best Concrete Tile Grout Cleaners in 2026

BUKKI's mold stain remover gel does what most bathroom sprays can't: it stays put. Squeeze a bead along grout lines, caulk seams, or the rubber gasket of a front loader, and the thick formula clings instead of running down the wall, so it keeps working on set-in mildew through the one-to-three hours it needs. I tried it on soap scum and hard water spots as well, and both lifted without scrubbing. It's bleach-free, fragrance-free, and non-abrasive, so colored grout and caulk come out of it fine. Seven ounces sounds small, but a little goes a long way.

No more scrubbing mildew and mold stains all afternoon. Now it's just spray and let it be. This PRO version is double strength of their standard outdoor cleaner.

Because it's a gel rather than a thin spray, it clings where you put it instead of evaporating off the tile, so it keeps working the whole time you're ignoring it. I've used it on bathroom tile, the tub, kitchen counters, and the silicone sealant around the sink, and it handled all of them without drama. Ten fluid ounces goes a long way since you're only applying it where you need it.
