[C320-list] Clean Propellers

FWIW
I put on a dive mask and using the scraper on my grill brush, knock
them off a couple times a season. They don't grow much in the Winter
and we use Commitment year round, so it works for us.

I grease the gears on my Gori 3-blade folding prop with thick marine gear grease and the gears are *totally* free of grease when I haul 6 mos later, and they are fairly protected. I find it hard to believe that anything would stick to the blades themselves for long unless it had a great bond to the metal.
