Reply to "Cleaning passenger car wheels"

I have two pieces of junk 30-inch Fastrack. I put a paper towel double thickness on the first one and wet it with Goo Gone. I push the car back and forth moving the paper towel to a clean spot every so often. When I feel it's clean I run it across the other piece of track with a new piece of paper towel to remove any residual dirt and Goo Gone.
