I think I put about 3.5 gal in a 30 gal garbage can with a tight fitting lid (Keeps the stench down till you take stuff out), so thats about 9:1 which is what I'd read most often.
Yep the whole enchilada all at once for a week.
Took it out and hosed it off, got the screws out (almost all anyway) and put the pieces back for another week or more.
The copper come clean quicker than the metal.

The Motor? Like I said I haven't taken the motor apart yet but I'd bet it works as it sits if I gave it the juice.
I rinsed the crap out of it spinning the squirrel cage with the hose and generally abused it, then set it out to dry for a day or four.

I'll let ya'll know when I tear into it and what I find.

Give me ambiguity
or give me something else
