acid dipping rust removal

Yep the mutiatic acid works great, but does require lots of neutralizing steps.

I read about the molasses method called chelation. Once it gets past the rust it stops once it hits bare metal. The muriatic acid does not. It keeps going and will continue to eat steel and cast iron if the parts are left in there too long.

With the molasses theres no noxious gasses to damage your lungs, or cause flash rust to everything near where your working with it since its not an acid, plus its biodegradable whereas the muriatic acid is not.

A simple hot water rinse, and blow dry is all thats needed with the molasses. One gallon of molasses to 9 gallons of water is all thats needed along with time to let it do its thing. Its not as fast as the acid, but works just as good, without the hazmat precautions, and disposal of the acid.
