Thanks for all the great info. When you use Muratic acid, do you just
dip the piece or soak it...for how long?

It typically takes less than 10 minutes. I arrange a plastic peanut-butter
jar on the ground, stick a few pieces of tubing in it and prop them up
really well, and then pour about 5 inches of muriatic acid into the jar.
It's quick in the summer, slower in the winter.

Don't do this in your shop. The hydrochloric acid vapor will leave a fine
layer of rust over every bedway, every exposed spindle, and any other piece
of steel in the entire shop, in just hours. No kidding. This is for
outdoors.
