Discovered in 1818, Hydrogen Peroxide use has become a staple in households around the world. The familiar brown bottle can be found nearly everywhere and used for everything from disinfecting to plant growth.

The most common versions sold over the counter is the 3% solution for household use and a 6% to 10% used in some hair coloring products. Higher concentrations of food-grade 35% and industrial 90% are also available but require special care and handling. Always remember hydrogen peroxide is not safe to be ingested, and high concentrations should be handled carefully and with appropriate protective equipment.

The signature “fizz” means it’s still working, but if you don’t see that,  it does not mean it has gone bad. The dark brown color of the bottle keeps light from entering and causing it to break down. While hydrogen peroxide is light sensitive, its is not as sensitive as people think. It is particularly sensitive to direct sunlight, specifically UV Rays. Room light will do little to no damage to the peroxide. Be sure to store it in a cool, dark, dry place, and it is best in the first few months after it’s been opened if it is a lower strength solution like 3%.

There are many uses for hydrogen peroxide for your health, in your home, and outdoors. It is a common ingredient in cleaning solutions, hair bleaching or lightening products, and medical treatments. Below are 50 ways you can use hydrogen peroxide and a few unexpected places it can be found.

31. Keep Your Fish Tanks Clean of Bacteria and Fungus

50 Hidden Hydrogen Peroxide Uses 18


When cleaning your tank, a few drops of hydrogen peroxide mixed in will help control the fungus that may be growing as well as bacteria. It should be used sparingly if fish are present in the tank. Still, the oxygen released during the reaction process can actually be a boost, particularly if algae is being removed.

You can also put your aquarium plants into a mixture of 2-3ml of 3% hydrogen peroxide per gallon of water to help them with algae, bacteria, and parasites. Submerge them for no more than 5 minutes. (Particularly effective against the pervasive black beard algae)

For help with removing large areas of algae in outdoor ponds, a higher concentration of hydrogen peroxide can be used, but strict guidelines should be followed as well as all safety information.

32. Boost the Health of Your Fish

As hydrogen peroxide decomposes, when exposed to a particular catalyst like air or light, it separates into plain water and an extra molecule of oxygen. These extra molecules can provide extra oxygen to small fish. The chemical reaction itself will also remove microbes that can affect the health of freshwater fish.

33. Brighten Up Tile Grout

50 Hidden Hydrogen Peroxide Uses 19

Over time your grout can get dirt ground into it, or liquids may get sullied, causing discoloration. To clean it and brighten your grout, you can make a paste with baking soda and scrub with a brush for smaller patches or pour the hydrogen peroxide directly onto grout in larger areas and let it sit, then rinse off with plain water. The best part of hydrogen peroxide is that once it begins to break down after use, it leaves no harmful residue and becomes plain water.

34. Put a Shine on Your Mirrors

50 Hidden Hydrogen Peroxide Uses 20

Leave a streak-free shine on mirrors and windows with a spray bottle of hydrogen peroxide. It uses no harsh chemicals and has no residue.

Tip: Old-school newspaper is still one of the best things to use, but if you don’t have any newspaper, a microfiber rag works best. Newspaper is made from recycled paper turned into a mulch multiple times, so the scratchiness of regular paper is pretty well gone.

35. Get Rid of Dust Mites in Your Mattress

50 Hidden Hydrogen Peroxide Uses 21


Your mattress should be aired out each day to help prevent dust mites from multiplying in your bed and to help disinfect it, a diluted solution of hydrogen peroxide and essential oils in water can be used to spray the surface, getting rid of dust mites, bacteria, and leaving a pleasant smell behind.

36. Cleaning Kids’ Items and Pet Toys

50 Hidden Hydrogen Peroxide Uses 22


Hydrogen peroxide is a great option to use on toys and in kid-safe spaces as it won’t leave behind any chemical residue. Wiping or spraying down areas where kids and pets play with a diluted mixture will leave the area clean and fresh.

38. Sanitize Your Humidifier and Dehumidifier

50 Hidden Hydrogen Peroxide Uses 23


Bacteria, mold, or mildew that may grow inside your machines can be taken care of by spraying them down with hydrogen peroxide.

Guidelines for CPAP breathing machines will give approved methods of cleaning the tunes and water reservoirs. You can use hydrogen peroxide in a diluted mix with water as a good option for disinfecting the equipment as well as the face mask. The face mask, in particular, comes into contact with both skin bacteria on your face, but it is also exposed to bacteria from your mouth and should therefore be wiped down after each use if possible.

39. Hydroponics

50 Hidden Hydrogen Peroxide Uses 24

The reservoirs in hydroponic systems should be regularly cleaned. One option is to use fresh distilled water, for best results, and add 2-3 teaspoons of the 3% solution per gallon of water in the reservoir. Be extremely careful with amounts and, if possible, check your local hydroponics store for charts and measurements that may help. A carefully added amount can result in healthier plants with improved growth and yield.

40. Help Your Garden Grow

Spraying Hydrogen Peroxide on Plants

Adding hydrogen peroxide to your garden can improve growth and help get rid of pests. Add one teaspoon to one cup of water and spray. The extra oxygen that comes from it in the soil can also help plants absorb more nutrients.

Whenever you are using the 35% solution, be assured to follow all safety guidelines, and wear appropriate protective gear.

43. Skunk Smell

50 Hidden Hydrogen Peroxide Uses 26


The smell of skunk is one of the most difficult to remove. Make a mixture as outlined below and apply it to the affected person or animal, being careful not to leave it on too long on hair or fur to avoid lightening the color.

  • 1 Quart Hydrogen Peroxide
  • 1 Tsp of Dish Soap
  • 2 Quarts of Warm Water
  • ¼ Cup of Baking Soda

44. Enrich Your Plant Seeds

50 Hidden Hydrogen Peroxide Uses 27

Adding a few drops to the soil around your seedlings can provide a little additional oxygen helping them to take root. Spraying your seedlings while still in their pots will add a little moisture and oxygen to them, and once they can be planted in the ground, a little extra of one ounce per quart of water will help the root systems establish themselves.

45. Plant Health


When a pathogen attacks a plant, one of the first things it will do is produce hydrogen peroxide to strengthen the cell walls and create a barrier to prevent the pathogen from spreading. For this, you don’t need to do anything. It’s just an added bonus plants have figured out on their own!

46. What’s in a Glow Stick?

50 Hidden Hydrogen Peroxide Uses 28


For something a little more fun, the glow stick gets it’s signature “glow” from a chemical reaction. They are made with two containers, an outer flexible plastic case and a fragile glass case inside. The chemicals in the outer case are a base catalyst and a suitable dye; when the container is bent, the inner glass container breaks, mixing it’s chemical in with the others, causing the “glow.” The inner glass container is filled with – hydrogen peroxide!

Glow sticks are frequently used for fun at parties, concerts, and outdoor events at night. However, they are also used for search and rescue operations, as emergency light during power outages, and are especially useful underwater.

47. Water Purification

50 Hidden Hydrogen Peroxide Uses 29


A solution with low concentration can be used to disinfect water that has been contaminated with pathogens. High concentrations can be used with UV light to decontaminate water that has been polluted with industrial waste. Ongoing research into this field could have enormous implications for purifying large amounts of water.

Water. Researchers are actively investigating whether hydrogen peroxide could be a solution for getting purified water to remote areas of the world. Potable water is necessary for any community to thrive and yet attempts to bring in purifying equipment or chemicals have been extremely cost-prohibitive. Tests are being done now to alleviate that cost by turning contaminated water into hydrogen peroxide, then allowing the normal chemical reaction to take place, which would both purify and turn it back into plain water.

48. Rocket Fuel

50 Hidden Hydrogen Peroxide Uses 30


No, really. Concentrated hydrogen peroxide has been used as a propellant in rocket fuel. Also referred to as “High-Test Peroxide,” it is a reactive oxygen species that can be used as a propellant. The 90% concentration is remarkably stable and has been used by the Russian space force for the past few decades.

While not impossible to obtain, it is a little difficult and requires specific containment measures similar to storing gasoline or kerosene. While hydrogen peroxide is not flammable, the extreme oxidation can cause extreme burns on the skin. It does not ignite like the fuels the US space program uses to create the force necessary to lift a rocket. Instead, it is put in contact with a catalyst like silver to create an explosion of force and pressure.

Stunt cars, modified motorcycles, and jet pack experiments prefer to use the heavily concentrated hydrogen peroxide to fuel their propulsion systems as it is stable, will not catch on fire, and only leaves water as a residue.

Hydrogen peroxide is just water with some extra oxygen molecules attached, which makes it very unstable. It wants to get rid of those extra molecules as soon as possible, so it tends to react with a wide array of catalysts. Light, air, and heat alone are enough to make it revert just by themselves. So be sure to properly store your bottle and enjoy trying out a few of its benefits.

49. Chlorine Alternative

50 Hidden Hydrogen Peroxide Uses 31

Hydrogen peroxide is a versatile and eco-friendly alternative to chlorine in various applications. Its effectiveness as a disinfectant and sanitizer makes it a popular choice for pool and spa owners looking to maintain water quality without the harsh chemicals often associated with chlorine. Hydrogen peroxide effectively eliminates harmful microorganisms, algae, and organic contaminants in water, providing a safer and gentler option for swimmers and the environment. Moreover, hydrogen peroxide doesn’t produce the strong chemical odors or irritate the skin and eyes, offering a more pleasant swimming experience. Whether for pool maintenance, household cleaning, or wastewater treatment, hydrogen peroxide serves as a sustainable alternative to chlorine while ensuring clean, safe, and refreshing water.

50. Science Experiments

Hydrogen peroxide can be the star of a thrilling and educational science experiment, much like the famous “elephant toothpaste” demonstration. By combining hydrogen peroxide with a catalyst like potassium iodide or yeast, you can witness an exothermic reaction that results in an impressive foamy eruption. This visually captivating experiment showcases the rapid decomposition of hydrogen peroxide into water and oxygen gas, generating a dramatic explosion of foam. It’s a fantastic way to engage budding scientists, teaching them about chemical reactions, catalysts, and the properties of hydrogen peroxide—all while sparking their curiosity and enthusiasm for the world of science.
