Actually I have an altoids type tin in my toolbox full of corn starch. Sucks the fuel oil right off the bands quicker than anything Ive seen. I get 2 to three flights off my bands and in truth could probably go more, but as was stated earlier new bands are cheap insurance, so I don't push the envelope too far.

Now I must admit, Ive not seen the kitty litter used for this particular issue so I wont say its not just as good.
