Laundry de-odorizer: add 1/2 cup baking soda to a load before running a cycle.

Make your own glass cleaner: Mix 1/4 cup white vinegar with 3 cups of water in a spray bottle. Spray and wipe down with newspaper.

Never buy commercially produced glass cleaner again!

Toothpaste: mix one part sea salt to one part baking soda. Make a 50/50 mix of water and hydrogen peroxide, and then add enough of this to the salt and baking soda to form a paste like consistency. Add a few drops of pure peppermint oil.

Stop buying mass-produced toothpaste! The homemade stuff is cheaper and (in my experience) works better.
