Cleaning a Japanese teapot is easy. Fill it halfway with clean water, then shake the pot gently back and forth to get the leaves off the net. Then rinse with clean water. You only need to use dish soap about once in every 10 times you wash the teapot.
Matcha bowl- a little matcha powder will cling to the bottom of your bowl so wash with the dish soap of your choice. Then rinse it thoroughly with purified water.
To clean the whisk fill a bowl half-full of clean water and rotate the whisk. Or rotate it under the tap. Then rinse it gently with clean water.
After several uses, the bamboo will become stained green. This is normal, the whisk is still good. If you use a whisk twice a day, every day, your whisk should last 2 to 3 months.
