WD 40 uses
Winterproof boots and shoes Waterproof your winter boots and shoes by giving them a coat of WD-40. It’ll act as a barrier so water can’t penetrate the material. Also use WD-40 to remove ugly salt stains from boots and shoes during the winter months. Just spray WD-40 onto the stains and wipe with a clean rag. Your boots and shoes will look almost as good as new.
Clean toilet bowls You don’t need a bald genie or a specialized product to clean ugly gunk and lime stains from your toilet bowl. Use WD-40 instead: Spray it into the bowl for a couple of seconds and swish with a nylon toilet brush. The solvents in the WD-40 will help dissolve the gunk and lime. ~ReadersDigest Site
