There are a few things you can do to clean a wet car seat:

  1. Pour a pot of boiling water onto the seat and let it sit for a few minutes, then pour cold water over the area to cool.
  2. Use a vacuum cleaner with the hose attachment to suck up all of the water and dirt that has built up on the seat. Be careful not to damage the fabric or coverings.
  3. Use a dry cloth to clean the area, being careful not to damage the fabric or coverings.
