1. Clean the dirt on the surface in time
No matter leather shoes or leather clothes, they will be contaminated with dirt and dust as long as they are used. Therefore, they must be cleaned up every day after use. This can also prevent some dirt from staying on the leather for a long time, making it more difficult to clean the leather. When cleaning the surface, white vinegar can be used to mix with water, and then a cloth can be dipped on the leather to wipe off dirt and dust. If the dirt is serious and there is no proper detergent around, please send it to a professional organization for maintenance immediately.
2. Choose the right leather oil
If it is made of genuine leather, you can choose natural animal oil, such as mink oil or salmon nourishing oil, which can help maintain leather. Different brands of animal oil have different absorption and ductility. For example, mink oil is cheap and easy to use, but it is difficult to push evenly, and the absorption effect is poor. In addition, it is not recommended to choose leather oil containing wax. Although it will be very shiny when smeared, excessive wax will affect the air permeability and shorten the life of leather.
3. Small wear can be repaired naturally
If there are some small scratches on the leather, you can use your fingertips, palms or cotton cloth to gently and slowly wipe, dip a little leather oil, and push along the scratches to slowly eliminate the small scratches.
