My hack is even simpler. Let the Old Lady clean. 
Once in a while she gets so pissed I dont wash my truck, Ill get a free interior detailing service.
Lifes to short to waste it washing vehicles. Thats what the rain's for.

.After you got the rusted piston free,we'd run a ball hone or deglazer through the cylinder,and wire wheel the piston clean,and if they had enough money slap a set of new rings and bearings in it,and you be up and running for the summer for about a hundred bucks,if no money,we'd free up the rings and it'd go back together with hopes and prayers lol
