Soaking and cleaning with baking soda or oxygen bleach can effectively remove discoloration.
Please follow these steps:
Soak Method:
1. Fill a bowl with hot or lukewarm water and add baking soda or oxygen bleach.
(Be cautious of spills when using oxygen bleach.)
2. Place the mesh in the solution and let them soak until the water cools.
3. Once the water has cooled, discard it and rinse the parts thoroughly.
4. Wash with dish soap, rinse well, and allow to dry completely.
For stubborn stains, gently scrub the mesh with a toothbrush to help remove residue.
