Thread: Rust removal trick

Tweet

this is a good trick for light rust, and gunk removal, but it actually damages the metal.
there is a electrolisys trick that uses rebar, and a car battery/battery charger, and replaces the rust metal with fresh iron... I'll try and find the link... it actually converts the rust pits to fresh metal. I've not tried it, but it looks like a good deal.

A lot of guys with old flatheads use vinegar to clean out the blocks. Especially good if the car is running - fill up the cooling system and run the car. All the crap, rust, etc loosens and comes out.

Great tip with the vinegar, will have to try that one out in the near future.

I have done the electrolysis before with great results. It is not recommended to use it on load bearing parts because hydrogen embrittlement can occur
