1. Cooking Spray
Squeaky door? Spritz a little cooking spray on the hinge (have a paper towel ready to catch any drips), then swing the door back and forth to ensure the oil coats the hinge. You can also use it to lubricate keys that tend to stick in locks, remove bugs from your car bumper bar, and coat your hands before using your fingers to roll meatballs or shape burger patties (it’ll prevent the food from sticking to them). Believe it or not, it’ll even help your next manicure – a light spray over nail polish helps it to set and dry quicker.
