This simple method will help keep your windows fog-free. It's a fun one for the kids to try too; they might even consider doing it before you reach the car!

Use the other half of the potato if needed. If you're doing all of the windows, you'll probably need to use up both potato halves.

Be sure to use a clean potato, so wash it first if it is coated in soil.This is a good opportunity to use up an old potato that has started to sprout and is past its best.

This may also work temporarily as a way to keep the window rain-free if used on the outside. However, heavy rain will wash it off.

It may be a good idea to clean the windows first.If they're dirty, the potato will pick up the dirt and can leave a sticky film due to the grime. If washing first, ensure that the window is perfectly dry before using the potato trick.

This method can also be used to keep ski goggles from fogging up. Rub raw potato over the goggles when changing into your ski gear. Sure, you'll need to remember to cut a potato in half and pop it into a plastic bag before going to the ski field, but the clear vision will make it a worthwhile effort.
