If the Headlights Seem Dim
Apply the toothpaste to light lids with a lint-free paper towel, then rinse with a sponge and warm water. A light wash with toothpaste removes dirt without damaging the road surface.
When You’re Stuck in a Car
Please note that most cars have removable head restraints. If you cannot open a door or window, try opening a side window using the metal clips on the headrest. However, this is not possible in an underwater vehicle. The soft glass is intentionally made to be hard to break, good luck!
