Even better than WD40 (which sucks as everything equally) is a mix of ATF and Acetone for stuck bolts. From the store, pb blaster is the best. Wd40 stands for Water Displacer, it is not the formula our fathers knew. They would have used wax and a torch or wintergreen oil anyway.

If for some reason you don't have some ATF and acetone lying around, Kroil is the next best thing.
