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! Right now
I have all the parts from a 1923 gain drill. Will take me forever to sand
all those parts. Have 1/2 dozen old handsaws and other old axes etc, that
are really bad. Too give you an idea of what I'm doing. I have a sand
blaster but that suit gets awful hot here in south TX. I've read about the
battery charger and baking soda method, anyone know how large a charger is
needed and does it work or harm the parent metal?

I tried electrolytic method and found it cumbersome and inconsistent.

I use diluted muriatic acid these days and it works very well for
me. Easy and works in every crevice. The post-treatment handling is
all-important, basically you need to dry the part as soon as possible,
and either oil it or paint it depending on your use of it.
