1. Protein solution decontamination method: use a clean soft cloth dipped in protein solution to wipe, so as to decontaminate, and make the skin shiny, but also not damage the skin. Protein liquid is available in general supermarkets. If you don't have it in your home, you can use egg white instead.
2. Vaseline decontamination method: first wipe gently with wet cloth, then coat with vaseline, and then wipe repeatedly with soft cloth, so that the surface of the bag can be bright as new.
3. Use a wet towel dipped in toothpaste to wipe slowly, or use wind oil essence and fresh banana peel to wipe, the effect is good (the method can be used in the leather is not obvious first try)
