While cleaning PU leather, avoid using any cleaners that may cause a reaction with the material. Use fine-grit sandpaper, which you can purchase from a hardware store. Always sand in a circular motion with low pressure. Do not use abrasives or chemicals on PU leather. They will harm the material. Using a rotary sander will allow you to easily get rid of stains and minor dents.
