Now that we're veering this thread off topic, I'll contribute my cleaning secret: microfiber polishing cloth from Pep Boys. I suppose a Wal Mart one would work too in a pinch. I can wipe a plane down with no cleaner at all and get the covering squeaky clean after a day of flying. I'll spray it after with the orange stuff to get the oil out of the seams, but that's it. I watch guys tear off one paper towel right after the other and smear that castor all around while I do one wipe and it's over. After about 20 uses the rag gets saturated so I hand wash it with Dawn and then toss it in the laundry with hot water.
