How to clean the silicone protective sleeve?

The first and most effective method is to rinse with clean water:

If there is grease on the silicone sleeve, apply soapy water, wipe off the stain with a soft cloth, and then rinse it off with clean water. Wipe the water dry with a napkin or soft cloth, and dry it in a cool and ventilated place.

Note: 1. Do not expose to the sun. 2. Do not clean too frequently.

Second, use an eraser.

Third, clean it with alcohol or a little toothpaste. (use less)

Fourth, use transparent glue or tape to stick.
