I use this product for cleaning my track: go to an automotive section and get 'Interior Detail' cleaner, spray some on a cloth and wipe. Works very well with no residue. I happen to have the STP brand, but any detail cleaner would work.
Bonus: take an old cardboard style, like the Christmas Tree air freshner(when it is exhausted), and put a few drops(or a lot) of you favorite smoke fluid scent on and you could have a nice smelling air freshner.
