I have had some success with Krud Kutter (Must for Rust). It is a vicious
stuff as far as smell, though...

LPS 1 and bronze wool on machined surfaces followed by LPS 2, or LPS 3
if it's not going to be used for awhile. You have to get rid of the
rust first before using the higher LPS numbers. Cast iron is porous
and rust will frequently "hide out" and come back no matter what you
do. You just have to be vigilant. "Rust never sleeps"! You can also
get rust from leaky shipping containers, salt water is particularly
bad, once exposed, iron just keeps rusting up no matter what you do,
chloride is hard to get rid of. If it's on a once-painted area, you
can use phosphating converter solutions that will be a long-term cure
for it as long as they're properly applied and repainted.

Please log in for more thread options after removing rust, apply shell SDB oil - it leaves a waxy corrosion
blocking film, that is it's job in life
