Hydrogen peroxide, a simple, inexpensive yet effective cleaning agent with disinfecting, whitening, and sanitizing properties, is a must-have in my cleaning arsenal.
While it’s generally safe, you need to handle it carefully and avoid ingesting it. Always wear gloves when using hydrogen peroxide, and ensure proper ventilation. In this post, I will discuss 26 effective uses of hydrogen peroxide in cleaning.
Practical uses of hydrogen peroxide for cleaning
1. Disinfecting countertops
Hydrogen peroxide is excellent for cleaning and disinfecting granite and quartz countertops. I usually mix equal parts hydrogen peroxide and water, and a few drops of dish soap. Apply the mixture to the surfaces and let it sit for 2-3 minutes before cleaning and wiping them.
2. Cleaning tile and grout
Mix hydrogen peroxide with a few drops of dish soap and apply it directly on the grout lines. Let the mixture sit for a few minutes to allow the stains to dissolve, then scrub with a grout brush or an old toothbrush, rinse, and dry. Hydrogen peroxide also helps to whiten the grout and prevent mold.
3. Removing mold and mildew in the shower.
Spray 3% hydrogen peroxide onto the affected areas and let it sit for 10-20 minutes before scrubbing and wiping them clean.
4. Degreasing kitchen appliances
Mix hydrogen peroxide, baking soda, and dish soap to form a thick paste. Use the mixture to break down and cut through grease and stains on stovetops, range hoods, and appliances. Make sure to rinse thoroughly after cleaning.
5. Cleaning glass and mirrors
Pour hydrogen peroxide into a spray bottle and add a small amount of water to dilute it. Use it to clean and wipe the glass windows or mirrors with an e-cloth or a lint-free glass cloth to remove streaks and smudges.
6. Remove stains from the floor rugs, carpets, and upholstery
Apply hydrogen peroxide directly to the stained area and let it sit for a few minutes before gently dabbing the area with a clean cloth.
7. Disinfecting toothbrushes
To kill germs and bacteria, soak toothbrushes in a mixture of equal parts hydrogen peroxide and water for 10-15 minutes. Rinse the brushes with water before using or storing them.
8. Cleaning and deodorizing cutting boards
Spritz hydrogen peroxide onto your cutting boards, let it sit for a few minutes or until it spritzes, and then rinse it with clean water. Hydrogen peroxide helps disinfect and remove odors.
9. Removing pet stains and odors
Soak the stained areas with hydrogen peroxide and let them sit for a few minutes before blotting or cleaning them with a clean cloth.
10. Cleaning and disinfecting humidifiers
To prevent mold and bacteria growth, add a mixture of 4 parts distilled water and 1 part hydrogen peroxide to the humidifier and let it sit for 30 minutes before emptying it.
11. Disinfecting sponges and dishcloths
Soak sponges and dishcloths in a mixture of water and hydrogen peroxide for 10-15 minutes to kill bacteria and eliminate odors. Rinse and dry thoroughly thereafter.
12. Removing soap scum in the shower
Mix a runny paste of 2 parts hydrogen peroxide and 1 part baking soda and apply it to the surfaces. Let it sit for 20-30 minutes to allow the soap scum to break down. Scrub and rinse the surfaces well to remove all the soap scum.
13. Cleaning and disinfecting makeup brushes
To disinfect your makeup brushes, soak them in a mixture of baby shampoo, hydrogen peroxide, and warm water. Rinse, dry, and store them properly.

Add a quarter cup of hydrogen peroxide to the top rack of your dishwasher and run it on the empty high setting to disinfect, kill germs, and remove odors.
20. Clean toilet bowls
You don’t have to rely on commercial toilet bowl cleaners to clean your toilet. I make my toilet bowl cleaner and disinfectant from a mixture of equal parts of dish soap and hydrogen peroxide. I pour the solution into the bowl, let it sit for 15-20 minutes, then scrub with a toilet brush and flash. Hydrogen peroxide not only sanitizes the bowl but also disinfects it.
21. Cleaning fresh produce
To sanitize fresh fruits and vegetables, soak them in a solution of 1/2 cup of hydrogen peroxide and a gallon of water for at least 30 minutes before washing. Hydrogen peroxide may also help remove dirt and pesticides from the produce.
22. Disinfect Children’s toys
Hydrogen peroxide is excellent for sanitizing and disinfecting children’s toys, especially after playdates or when toys have been shared among multiple children. To disinfect toys, soak them in a solution of equal parts water and hydrogen peroxide. Rinse and dry.
23. Clean Sinks and faucets

Use hydrogen peroxide to clean, remove stains, and shine sinks and faucet handles. I usually mix 1/2 part baking soda, 1 part hydrogen peroxide, and a few drops of dish soap to create a paste. I then apply it to the sink or faucet and let it sit for a few minutes before washing it off.
24. Laundry
Add hydrogen peroxide to the dirty laundry to help remove odors, whiten and brighten bright-colored clothes, and remove stains. Add 1/2 cup of 3% hydrogen peroxide and your regular laundry detergent to your load.

26. Cleaning garden tools
Hydrogen peroxide is excellent for disinfecting and cleaning gardening tools. It can help prevent the spread of fungus, bacteria, and viruses. Rinse your gardening tools in a mixture of equal parts water and hydrogen peroxide before storing them for the next job.
Frequently Asked Questions
Do I need to dilute hydrogen peroxide for cleaning?
Hydrogen peroxide is generally safe; however, depending on the strength of your product, you may need to dilute it to a suitable concentration for use. For instance, 3% hydrogen peroxide is already diluted in a ratio of 97% water and 3% hydrogen peroxide; therefore, it is unnecessary to dilute it further. Food-grade hydrogen peroxide is more potent and may need to be diluted before use in cleaning applications.
What can you mix with hydrogen peroxide for cleaning?
You can safely mix hydrogen peroxide with various cleaning agents, such as water, baking soda, and dish soap, to achieve more potent effects.
What can’t you mix with hydrogen peroxide?
Never mix hydrogen peroxide with vinegar, ammonia, or bleach, as this can produce harmful substances that can be toxic to your respiratory system, skin, and eyes.
Always test a small, inconspicuous area before using hydrogen peroxide on a surface to ensure compatibility and avoid any potential damage.
