Some unique ways that WD-40 can be used include protecting a bird feeder from squirrels, removing a stuck-on ring, and exterminating and repelling insects. Another unique use for WD-40 is removing gum from a carpet or hair.
WD-40 applied to the top of a bird feeder makes the surface too slippery for squirrels and other creatures to grip, leaving the seed inside the feeder for birds to eat as intended. Spray a generous amount of WD-40 around a stuck-on ring to allow it to slide right off without damaging the jewelry. Spray WD-40 on windowsills and in door jams and cracks to repel spiders and other insects from entering the home.
