Toothpaste
Toothpaste does more than just keeping our teeth bright and white. It can be used wisely in many other ways. Here are some useful tips that can save us time and money, and leave a fresh smell—using toothpaste!
Clean a Dirty Mirror
If you want to clean a dirty bathroom mirror, try to put a bit of toothpaste on the mirror and wipe it. The glass can be cleaned up beautifully. And doing this can also stop the mirror from fogging. Then you can still see yourself in the mirror after taking a shower.
Remove the Unpleasant Food Smell
