1. Cleaning: First, dip a clean soft cloth in a proper amount of leather cleaner or furniture care oil, and gently wipe the surface of the leather chair to remove dust and dirt. Be careful not to wipe hard to avoid damaging the cortex.

2. Patch: Stick it on the peeling part with a special leather patch or liquid glue. Apply the repair paste or glue evenly to the peeling part, and then flatten it with a finger or scraper to ensure that the repair material is in full contact with the leather surface. After the repair material is dried, wipe the surface with a clean soft cloth to make it flush with the surrounding leather surface.

3. Coloring: If the peeling part is large, consider coloring to make the repaired color consistent with the surrounding leather surface. Special leather dyes or pigments can be used and prepared according to the product instructions. Apply the dye or pigment evenly on the peeling part, and then push it away evenly with your fingers or a soft cloth to let the color penetrate into the cortex. After the dye or pigment is dried, wipe the surface with a clean soft cloth to make it flush with the surrounding leather surface.

4. Protection: After the repair is completed, the leather surface can be maintained with a special leather maintenance agent to enhance the wear resistance and scratch resistance of the leather. Apply the maintenance agent evenly on the leather surface, and then wipe it clean with a clean soft cloth.

5. Regular inspection: In daily use, it is necessary to regularly check the wear and tear of leather chairs and find and deal with problems in time. Avoid scratching the cortex with hard objects, so as not to affect the appearance and service life.
