Stickers on a windshield can be really hard to remove. Put a cloth soaked in hot water on the sticker from the opposite side of the windshield. When it cools down, the glue will dissolve and the sticker will be way easier to remove.
5. Nail polish
If you notice a crack on the windshield, you can easily paint over it with nail polish. It will prevent the crack from getting bigger so you will be able to get to your destination safely.
6. A plunger
If there is a small dent on the car, you can use a plunger to remove it. It really works! Just place it on the dent and pull it. Your car will be as good as new.
