TL;DR

• Rinse bristles in warm water after each use.
• Shake off excess, air-dry bristle-side up.
• Store in a dry place; keep out of direct sun & high heat.

Step-by-step routine

1. Rinse: Run warm water through the bristle bed to flush dirt.
2. Squeeze: Press bristles gently to expel water.
3. Dry: Stand the brush on its back edge or hang by the pole to let air circulate.

Why avoid soaking?

Leaving the polybutylene terephthalate bristles submerged can warp plastic and soften bristles, shortening their useful life.
