Now we're going to refinish the window lift mechanisms. If the window lifts aren't badly rusted, Mike completely restores them with this acid-based "wire and mag wheel cleaner." Similar products are available at any auto parts store. Make sure you get an acid-based cleaner, to help remove any rust from the parts, in addition to all the old lubricant and dirt. Also be sure to wear heavy rubber gloves when using any type of cleaner like this, and don't breathe the fumes.
