I religiously wipe a damp cloth over:
Prop
Leading edges of wings
Spats
Wing struts
Front of cowling
Windscreen
as soon as I return drom flying in the spring/summer and then run around the same areas with a chamois.
It takes 5 minutes and makes going flying in a clean plane the next time that much more of a pleasure.
Perhaps I am a sad git but it pleases me.....
