What's your rust removal method?

EDIT: Either for tools or for frame or whatever else

I've heard/read of:

lemon juice (citric acid) & salt

lemon juice (citric acid) & baking soda

White vinegar (acetic acid) & salt

White vinegar (acetic acid) & baking soda

WD-40 (water displacement perfected on 40th try)

Then you scrub with some steel wool or what not. Neutralize solution with some soapy water or baking soda and dry. Then put some WD-40, oil, or some other rust inhibitor to protect.

 

I used wire wheels on a drill and 80 grit sandpaper where I couldn't fit the driill, followed by Zero rust paint on my frame. Zero rust requires minimal prep work, just spray with water and let it dry 24 hours. It has held up pretty well so far. Definitely better then the areas I did with wire wheels/ 80 grit, laquer thinner and rustoleum.

 

Ospho is good. It is phosphoric and other acids. Turns the rust white. It changes from iron oxide to magnetite, so it's actually not rust anymore. Ospho can be found at the auto parts or hardware store. It's also called metal prep used by restoration and body shops. Just spray it on with a spray bottle...wear gloves though.

WD-40 and Rustoleum are both fish oil based, it stops rust.
