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 don't know. Never tried to make it.

Phosphoric acid is 25 - 30%. Water, fumed silica, isopropyl alcohol. A
little dab of surfactant and sulfuric acid.
