Was wondering what others use for dealing with rusted and/or corroded parts that are stubborn to separate or loosen? There are several types of lubricates and grim eaters, as well as using heat with them.
I know PB Blaster is often recommended, but I've wondered if CLR would also do a decent job on removing rust and corrosion. Other then potentially damaging paint or finish, which may sometimes not be a concern anyways, would CLR work fine?
