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.
Long bristles for larger grout areas, short bristles for corners and tight spots. Built for daily and deep cleans.
