I had struggled with this until today. Seemed like anything I tryed just left streaks and the towel was sooo tacky on the rubbery surface, it just did not work well. Today I tryed using Zaino's leather treatment applied with a clean cotton diaper. WOW. It did a great job of cleaning things up without making them shiney, and the diaper slid smoothly around on the surfaces. Took the scuff marks right off of the door too! Looks better than new now, and that sticky rubbery feel is also gone. This will be SOP for me going forward. Just thought I would share.........
