New Member here! Hello all!
Anyone have a cheap (reasonable) recipe for a chemical rust remover that
can be used in removing medium to heavy rust? I'm always restoring or
reclying something that has rusted. I'm aware of the dangers that can be
involved. We used to do plating, etc. in the shop I worked in. Jenolite or
Naval Jelly is made from what? I was told they contain Phosphoric acid,
but what percentage?
I'm not in a hurry, so even a "greener" solution would be okay!
-----------
Be remined that Naval Jelly does not remove rust but converts it
from the red to black oxide. Best solution appears to be
electrolitic cleaning. Use a plastic storage container from
walmart for the tank and your battery charger. Several threads
on this in this NG.

Usual solution is washing soda [baking soda also works] at the
rate of a tablespoon to the gallon, which is pretty tame.
