Ron, the newer gaskets are maintained with soap and water for cleaning. Then a light coat of silicone sprayed on a clean cloth and applied to the outer surfaces (where the gasket contacts the door or windows) will keep them from sticking and also add years to their service life. Hope this helps. Happy trails, Ed
