there are a whole bunch of car ones that are literally the worst- don’t try any of these at home:
Use hot water to quickly de-ice a windshield
To keep your brakes from sticking oil the rotors
Add some nails to each tire for better traction on ice
Put a warm wet towel on your windshield overnight to keep it warm
Keep your headlights on overnight to keep them from freezing over
Put sandpaper on your windshield wipers to assist in ice removal
Loosen your lug nuts in advance in case you end up getting a flat tire
Block the exhaust pipe with a tennis ball to keep the car warmer (this one is extremely dangerous; for anyone not aware every year there are people who die from not shoveling snow away from the exhaust pipe prior to turning the engine on)
