A molases bath is also a good way to de rust parts.

Mix the molases 1:1 with water in a tub. Submerge rusty bit. Rust comes off, takes time. Get dog to lick part clean.


Nah, wash it with water. Dry and paint.
Seen pictures etc in a Hot rod magazine. Think i also read something on a how to website. Looks the goods, low tech, works and non toxic.
