Rock Spot On Shoes

You stopped wearing your favorite sneaker because it has a stubborn rock salt spot? No matter how much you washed it but the stain stayed put and it was you who ultimately had to give up. Well, it is the time to go back at the spot with hammer and tongs, no, just go with WD-40. That would do the work. Just spray ED-40 on the good and wipe them off with a cloth. You can even make your shoe waterproof by spraying it over the whole of the surface.
