[ursus]

Any block that has been marinated in a gallon of muriatic needs to be rinsed well then marinated again in a solution of one pound of baking soda per gallon of water to neutralize the acid. As noted by a previous writer, muriatic acid will just keep on dissolving iron if not neutralized.

I saw a low mileage but very rusty diamond Model B block that received a stout bath in muriatic acid continue to dissolve over the course of a year. The guy that owned it commented on all the rust that fell out of it every time he moved it. By the time he took it in for boring and rebabbitting there were pin holes appearing in the top deck.
