14 car hacks every driver should know
MORE AT BUSINESS INSIDER
For as long as there have been cars on the road, there have been innovative car owners who have thought of some truly ingenious solutions to their car woes.
We came up with 14 awesome car hacks that may make your next car ride a little more pleasant (thanks to Farmers Insurance for the idea).
1. De-ice your locks with hand sanitizer.
Car locks can ice over in the winter. So squirt a little waterless hand sanitizer on your key and insert it in the lock. The same alcohol content that kills germs on dirty hands also melts away the ice in the lock.
2. Remove dents with dry ice.
The extreme cold of dry ice can help pop out dents. Pick some up at your local grocery store. Remember to pick it up with gloves, since dry ice can hurt your skin. Then apply it to the dent repeatedly until it’s gone.
3. Clean your engine with soap and water.
A spotless engine is easier to service. Clean it often with water and a little dishwasher detergent (degreaser works well, too). First, cover all the sensitive areas (electrical parts, battery, air intake, and distributor) with plastic bags, then scrub and rinse the engine with a soft rag. Remember to remove all plastic bags once you’ve cleaned all the necessary surfaces.
4. Fix scratches with nail polish.
Touch-up paint always works best, but if you’re in a pinch, clear nail polish helps to fill in scratches and cover up exposed metal to avoid rust.
5. Unlock your car with a shoelace.
Locking yourself out of your car is always frustrating and a little embarrassing. But don’t let it ruin your day. Tie a loop in a shoelace large enough to wrap around your door lock. Work it into the space between the car and the door, then move it until the loop fits around the door lock. Lasso it, and lift up the lock. This only works for cars with upper lock mechanisms. You can always call a roadside assistance service to help get your door unlocked, too.
