Use diluted muratic acid. Pour in the water first, then add the acid, then
dunk in the parts. Store in a safe manner. Do not store near ANYTHING that will rust!
Use at your own risk.
I take NO responsibility for this advice.
I reject your reality and substitute my own.
Well said, I was going to suggest it also, since I use it myself, but am always reluctant to suggest it to someone I don't know. Nice thing is it's cheap enough that you can buy a couple gallons and pour it into a PLASTIC pan like a oil change pan or something and just set the parts in and let them soak for a while. It gets into nooks and crannys where brushes can't go. Do it in a well ventilated area, and where it's safe from kids and pets, and just be careful.
