If you drink matcha daily, give your tools a quick check once a week.

• Whisk: Check for bent or broken tines. If damaged, replace it—it won't froth properly.
• Matcha powder: Store it in an airtight tin, away from light and heat. If it loses its bright green color or smells dull, it's past its prime.
• Bowl: Make sure it's clean and dry. Residual moisture can cause the powder to stick.

A quick rinse and air-dry after each use keeps everything fresh. Avoid soap on your bamboo whisk; just rinse with water and let it dry upright.
