1. Protein solution decontamination method: Wipe the protein solution with a clean soft cloth, so that the stain can be decontaminated, and the surface of the bag can be brightened without damaging the leather surface. Protein liquids can be bought in large supermarkets. If you don't have them at home, you can use egg whites instead.
2. Vaseline decontamination method: first wipe gently with a damp cloth, then apply a layer of Vaseline, and then wipe it repeatedly with a soft cloth, so that the surface of the bag can be as bright as new.
3. Use a wet wipe to rub the toothpaste slowly, or rub with a wind oil and a fresh banana peel. You can try it first when the leather is not obvious. The effect is good.
4. Leather bags are most afraid of water, wet and hard, and scratches on the leather surface. If your bag is contaminated or soaked, use the toilet paper or towel as soon as possible and dry it with a hair dryer.
