The best all purpose oil for EVERYTHING! This should replace all other oils and lubes in your house! Use cases we’ve used this for over the years: removing rusty bolts, bike chain and bearing lubrication, treating rusting tools for storage during the winter, sewing machine oil, door hinges, squeaky dresser drawers, pretty much anything that moves with metal on metal. We even used it on a sticky vinyl window to help loosen it so it would open easier.
