How do I care for Koh Grout Brush?Updated 10 days ago
TL;DR: Rinse Grout Brush bristles in warm water after each use, squeeze gently, and air-dry bristles-up. Store in a dry place away from direct sun and high heat. Don't soak.
How do I clean Grout Brush after each use?
Rinse warm. Run warm water through the bristle bed to flush out dirt and cleaner residue.
Squeeze gently. Press the bristles to push water out. Don't twist or wring.
Air-dry bristles-up. Stand the brush on its back edge or hang it by Grout Brush Pole so air circulates.
Can I soak Grout Brush?
⚠ Don't soak
PBT bristles soften, warp, and splay if left submerged. That ruins the precise bristle angle that bites into grout channels. Rinse only, don't soak.
✓ Rinse and dry
A 10-second warm rinse through the bristle bed, a gentle squeeze, and a bristles-up air-dry. That's the entire care routine.
How should I store Grout Brush?
✓ Best storage spots
Shaded cupboard, utility drawer, cleaning caddy, or laundry shelf. Anywhere dry and out of direct sunlight keeps bristles straight and strong.
⚠ Avoid
Direct sunlight, hot windowsills, above radiators, next to ovens, in the car boot, or sealed inside a damp plastic bag. UV and heat degrade the bristles over time.
Grab a fresh one when bristles splay or flatten beyond reshaping.
Hang Grout Brush off it to air-dry. Doubles as a standing-scrub handle for floor grout.
