Peroxide

3% peroxide

No more canker sores and your teeth will be whiter without expensive pastes. Use it instead of mouthwash. (Small print says mouth wash and gargle right on the bottle)
Soak any infections or cuts in 3% peroxide for five to ten minutes several times a day
Fill a spray bottle with a 50/50 mixture of peroxide and water and keep it in every bathroom to disinfect without harming your septic system like bleach or most other disinfectants will
You can also add a cup of peroxide instead of bleach to a load of whites in your laundry to whiten them. If there is blood on clothing, pour directly on the soiled spot. Let it sit for a minute, then rub it and rinse with cold water. Repeat if necessary.
