How to Care for Your Bamboo Matcha Whisk (Chasen)
A bamboo matcha whisk, or chasen, is an essential tool for making perfectly frothy matcha. With proper care, your whisk can last for months and continue to create smooth, well-mixed matcha. But if not cared for properly, its delicate tines can break, fray, or lose their shape over time. Additionally, using too much force while whisking can strain and break the delicate tines.
Here’s a quick guide to keeping your bamboo matcha whisk in top condition.
6 Simple Steps to Care for Your Matcha Whisk
1. Soak Before First Use (or When Needed)
If you’re using your brand-new bamboo whisk, soak it in warm water for a couple of minutes before the first use. This softens and expands the prongs, making them more flexible and less likely to break. You can also do this occasionally if your whisk starts to feel dry or stiff.
To learn how the number of prongs can affect your matcha texture and flavour, make sure to take a look at our article "Comparing Matcha Bamboo Whisks: 80, 100 & 120 Prong Chasens."
2. Rinse Immediately After Use
After whisking your matcha, rinse the chasen under warm running water. Avoid soap or harsh detergents, as they can weaken the bamboo fibres. Never use a dishwasher – it can damage the delicate structure of the whisk.
You could also gently whisk it in clean warm water to remove any remaining matcha.
3. Shake Off Excess Water
After rinsing, lightly shake off any remaining water. This helps prevent excess moisture from lingering, which could lead to mould growth.
4. Air Dry Properly
Place your whisk with the prongs pointing downwards on a whisk stand or a clean surface. This allows it to air dry completely and prevents water from collecting at the base, which can lead to mould.
5. Store Upright Once Dry
Once fully dry, store your whisk upright with the prongs facing upwards or in a whisk holder. This helps maintain its shape and prevents moisture buildup.
6. Whisk It Right
Avoid using excessive force while whisking. Instead, use a gentle, quick zigzag motion (M or W shape) to create a frothy matcha without straining the tines.

FAQs: Bamboo Whisk Care
How often should I replace my matcha whisk?
It really depends on how often you use the chasen and how you treat it. With regular use but proper care, a bamboo whisk can typically last up to 1 year before the prongs begin to weaken or fray. If you notice the whisk losing its shape or struggling to create froth, it may be time for a replacement.
How do I prevent mould on my whisk?
To prevent mould, always rinse, shake off excess water, and dry the whisk properly before storing it. Avoid keeping it in a sealed container or damp environment.
Can I put my matcha whisk in the dishwasher?
No, never put your chasen in the dishwasher. The heat and water pressure can damage the delicate bamboo and cause it to break.
Why are my whisk prongs bending outward?
Over time, the prongs naturally begin to spread out with use. This doesn’t affect its function, but if you want to maintain its original shape, store it in a whisk holder. Additionally, make sure to soak it in the warm water for 1-2 minutes for the first time you're using the whisk. And avoid excessive force while whisking. Try gentle, quick zigzag motion (M or W shape).
Can I use my whisk for other drinks?
A chasen is specifically designed for matcha. Using it for other liquids, especially thick ones, may damage the prongs or cause excessive wear.
What should I do if my whisk becomes misshapen?
Soak it in warm water for a few minutes, then gently reshape the tines with your fingers. Using a whisk holder can help maintain its form over time.
