Can Hydrogen Peroxide Bleach Carpet? What We Know

Cleaning your carpet can range from a weekly chore to an emergency clean-up, but it's nevertheless a necessary task. Whether you're blotting a spill or vacuuming up your pet's fur, doing this with at least some regularly is important. Carpets trap dust, dirt, allergens, and even bacteria over time, and this can compromise the indoor air quality of your home and lead to health risks, particularly for anyone with respiratory issues or allergies. Consequently, regularly cleaning your carpet – both through vacuuming and a deeper carpet clean — can help remove these irritants and elongate its lifespan. Hydrogen peroxide is one substance often used to clean carpets, but there is a valid concern that using this can bleach the colors from your rug.

Replacing flooring can be a huge expense, so it's understandable to question whether hydrogen peroxide is the right choice to clean your rugs. According to Better Bond Cleaning, hydrogen peroxide can be safe to clean your carpet. "Hydrogen peroxide has antimicrobial, oxidizing and bleaching properties that can help you remove carpet stains without causing any damage," the company wrote. 

The trick here seems to be that using a 3% peroxide solution and diluting it with water makes it safer to use on carpet stains without the risk of bleaching. Even with this endorsement, it's advisable to proceed with caution when using the bleaching power of peroxide, particularly when cleaning darker carpets, which are more likely to betray bleach marks.

To use hydrogen peroxide while avoiding any mistakes in cleaning your carpet, it's important to follow a few key steps. When working with this chemical, remember to dilute it properly. Prestige Carpet Cleaners recommends pairing it with baking soda and dish soap to remove carpet stains and relieve unpleasant odors. This solution should work on a number of common carpet stains like accidents from your pets, food and drink stains, dust residue, or even blood stains.

To get started, be sure the carpet is dry. Soak up any spills as best as you can with a clean cloth. Try dabbing the carpet rather than rubbing the cloth on it as this may spread out the stain. Sprinkle baking soda over your carpet on areas in need of treatment. Then mix ½ cup of 3% hydrogen peroxide with a teaspoon of dishwashing detergent in a spray bottle. For some added freshness, you can also add a few drops of your favorite essential oil. Lemon or lavender have bright, clean smells that will complement your freshly cleaned carpet. 

Give the spray bottle a vigorous shake to emulsify the liquids, apply the mixture to the stained area on your carpet with the baking soda, and allow it to sit for 15 minutes. Once it has sat, you can either wipe up or vacuum the cleaning solutions. Then dry any remaining moisture with a hair dryer or dab it with a clean towel.

While some companies, like Better Bond Cleaning, advocate for utilizing hydrogen peroxide to remove carpet stains, there are safer alternatives that you can use. Some carpets can be sensitive to the bleaching properties of peroxide. According to Prestige Carpet Cleaners, "it should not be more than 6% concentration. If you dare, all the color of your carpet will disappear and leave an ugly patch on it." Given that warning, it may be wise to try another option.

One safe and affordable alternative to hydrogen peroxide is white vinegar. Like peroxide, it's an all-natural, non-toxic cleaner that is also effective at breaking down stains, dissolving grease, and neutralizing common household odors. You can dilute vinegar with water with a 1:1 ratio and add it to a spray bottle to spray directly on carpet stains. Allow the mixture to sit for 10-15 minutes before blotting it dry with a clean towel. While vinegar is generally considered a safe carpet cleaner, it's still a good idea to check its compatibility with your type of carpet or test it in an inconspicuous area before tackling a large stain.

Finally, dish soap is another simple yet effective solution for treating carpet stains. Like vinegar, it can cut through grease and grime and tackle difficult stains that may leech into your carpet. Mix a few drops of dish soap with warm water and apply it to the stain with a spray bottle, then blot dry with a clean cloth.
