Shoulder bag cleaning

1. Protein Solution Decontamination Method: Use a clean, soft cloth dipped in a protein solution to wipe the surface. This will clean and polish the leather without damaging it. Protein solution can typically be found in supermarkets. If you don't have it at home, you can substitute it with egg white.

2. Vaseline Decontamination Method: Start by gently wiping the surface with a damp cloth. Then, apply a thin layer of Vaseline and repeatedly buff the leather with a soft cloth until the surface shines like new.

3. Toothpaste or Balm Essence Method: Dampen a cloth with a bit of toothpaste or balm essence and gently wipe the leather. Alternatively, you can use a fresh banana peel to rub the surface. It's recommended to test these methods on inconspicuous areas of the leather first, as they can produce good results.

4. Moisture Protection for Leather Bags: Leather bags are most prone to hardening and scratching when exposed to moisture. If your bag gets wet or stained, immediately wipe it with toilet paper or a towel, and then dry it using a hair dryer on a low setting.
