l have come across several threads in regards to cleanup of oil residue, grass, etc from plane covering - several good hints at home-made formulas and only a couple of readily available products... but usually main concern is cutting crud - a good thread that exists is l think before ULTRACOTE really came into popularity

what about cleaning off residues AND leaving a nice shine to the covering - and specifically ULTRACOTE?
l have been using a no-name window cleaner - with ammonia, which some feel is bad for electrical connections and making covering brittle - but as the ultracote ages it just doesnt clean up as nicely as when new - and mainly looking for a ready-to-use product

don't want to start trying different products/blends/etc and maybe harm the covering / sheen more - have a great looking plane and want it to stay that way
