Which Koh cleaners work best with Grout Brush?
Everyday grease, grime, and dirt on all grout types. Go-to pick for general floor and wall grout cleaning.
Soap scum, limescale, and hard water residue in bathroom grout. Best pick for shower walls, tiled floors, and around the bath.
Heavy kitchen grease build-up, splatter, and cooking oil residue in tight grout corners behind the stovetop, around rangehoods, and along splashbacks.
Which grout types and surfaces does Grout Brush work on?

✓ Ideal surfaces
Cement-based grout (sanded or unsanded), epoxy grout, textured porcelain, and matte ceramic tile. Stiff but flexible bristles bite into the channel without scratching surrounding tile.
⚠ Use with caution
Silicone and acrylic caulk is soft, so apply minimal pressure and short strokes. High-gloss marble, travertine, and polished natural stone can scratch if over-scrubbed. Spot test in a hidden corner before full scrubbing.

Grab a brush
Long bristles for larger grout areas, short bristles for corners and tight spots. Built to handle daily and deep cleans.
