Hydrogen peroxide is a must-have in your natural house cleaning kit thanks to its ability to deodorize, get rid of stains, kill germs, and tackle grime.
Hydrogen Peroxide Facts
Find a bottle of this inexpensive solution at your local grocery store or pharmacy, then keep it on hand to tackle a variety of household issues.
What is Hydrogen Peroxide?
Hydrogen peroxide is a colorless, liquid chemical compound that results from a combination of water and oxygen. The foam you see when it’s poured onto cuts or other surfaces is oxygen bubbles. It comes in several strengths and two grades.
Which Strength to Use?
Hydrogen peroxide comes in various strengths. The number tells you the ratio of hydrogen peroxide to water. So, the 6% hydrogen peroxide used in hair bleach is twice as strong as the 3% concentration used in first aid.
Household hydrogen peroxide is sold in brown bottles at grocery and drugstores. This type of hydrogen peroxide is 3% hydrogen peroxide and 97% water, making it safe yet effective.
The tips below are all based on using 3% hydrogen peroxide.
Three percent (3%) hydrogen peroxide is safe for household use. It is non-toxic if accidentally ingested in small quantities, though it may produce a lot of foam.
Hydrogen peroxide can be highly irritating if applied directly to the skin or accidentally splashed in your eyes. If that happens, flush the area immediately with water for several minutes. If your eyes are involved, call your doctor for further instructions.
Store hydrogen peroxide in its original brown bottle to protect it from light, which lowers its effectiveness. The bottle also contains safety instructions about what to do if you accidentally splash the liquid into your eyes or otherwise misuse it.
Hydrogen peroxide remains effective for approximately 6 months after opening. It’s helpful to write the date you opened the bottle somewhere on the container, so you always know when to discard any unused portion.
25 Ways to Use Hydrogen Peroxide
1. Pest-controlling plant booster. Give your houseplants a hit of extra oxygen and control pests at the same time. Just combine 1 teaspoon of hydrogen peroxide with 8 ounces of water and spray this solution on your plants.
2. Toothpaste: Make a paste of baking soda and hydrogen peroxide then brush your teeth. Or do as my grandma did and brush your teeth with the baking soda, then swish and spit the hydrogen peroxide. (Never swallow it!)
3. Clean and deodorize retainers: Your orthodontist wants you to wear your retainer, but eventually, it starts to stink. Clean and deodorize by soaking it for 30 minutes it in a glass filled with equal parts hydrogen peroxide and warm water.
4. Prevent “Swimmer’s Ear”: Mix equal parts hydrogen peroxide and white vinegar. Using an eyedropper, put 5 drops in each ear after swimming to kill the bacteria that cause this infection.

11. Clean earring posts: Wet a cotton ball with hydrogen peroxide and wipe the posts to remove dead skin and bacteria.
12. Diamond cleaner: Dip a soft toothbrush in hydrogen peroxide and use it to scrub diamonds, then rinse with fresh water. Do not use on silver, though. (Here’s how to get rid of tarnish on silver jewelry.)
