How to Properly Clean and Store a Chasen (Bamboo Whisk)

Clean promptly: Rinse immediately after use to prevent matcha residue from causing discoloration or mold.
Water temperature control: Use lukewarm water (approx. 30-40°C). Avoid hot water (may crack bamboo) or cold water (may cause shrinkage/deformation).
Gentle handling: Rinse bamboo tines softly with hands or a soft cloth. Never scrub forcefully or twist to prevent breakage.
Avoid chemicals: Do not use dish soap or detergents, as chemicals may corrode bamboo. Clean with water only.
Thorough drying: After rinsing, wipe surface moisture with a clean cloth and air-dry naturally (avoid direct sunlight). Ensure complete dryness to prevent mold.

Store only when completely dry: Ensure the whisk is fully dried before storage to avoid mold in humid conditions.
Ventilated, dry storage: Keep in a cool, ventilated area (e.g., tea utensil cabinet), away from humid spaces like kitchens or bathrooms.
Protect from light: Avoid direct sunlight to prevent bamboo from fading, becoming brittle, or deforming.
Use dedicated holders: Store in a tea whisk stand or specialized container to maintain tines’ natural spread and prevent bending/damage.
Regular inspection: Check monthly. Gently brush off mold spots with a soft brush if found; address cracks promptly. For long-term storage, wrap in an air-permeable cloth bag.
