Leatherette seats are a popular option on BMWs, and they can be a bit of a pain to clean. Here are some tips on how to clean them:

  1. Start by taking off the seat coverings. This will help you to get at the dirt and grease that is hiding under the fabric.
  2. Use a vacuum cleaner with low suction to suck up all of the dirt and grease that is hiding under the fabric. Be careful not to damage the fabric!
  3. Rinse off the seat with warm water and soap. Be sure to use plenty of soap, as it will take care of any dirt and grease that was missed in step 2.
