How to Get a Home Sparkling with Hydrogen Peroxide and Baking Soda

Stop wasting money on fancy, name brand cleaners that don’t work? Start using the hydrogen peroxide and baking soda powerhouse duo that’s hiding out in your pantry and medicine cabinet.

Hydrogen peroxide and baking soda can be mixed together to create the Superman of disinfectant cleaning solutions.

Besides whitening your teeth and freshening your breath, this duo can conquer some of your toughest cleaning jobs including baked-on grease, dingy grout, laundry stains, and hard water buildup.

I grew up using bleach and vinegar to clean everything. When I got my first apartment, I tried every fancy product on the market.

Most of them did a mediocre job if I could get past the strong smell. Some of them were so bad, they literally took my breath away, ust like the bleach and vinegar did.

The first time I tried hydrogen peroxide and baking soda to clean my toilet bowl was the day I threw out more than a dozen, barely used bottles of expensive cleaner. That toilet bowl was sparkling clean and I had barely started scrubbing.

Since then, it’s been one of my favorite cleaning tips to share with friends.

How Does Baking Soda and Hydrogen Peroxide Work?

There’s a super technical chemistry explanation for how these two work together, but I’m pretty sure I’d do a lousy job of explaining it. Instead, I’ll tell you my version.

Hydrogen peroxide is a strong oxidizer (bleach) and mild acid. It’s very effective at breaking down protein and plant-based stains including bacteria, fungi, and spores. This makes it a pretty effective cleaner all on its own.

Baking soda (sodium bicarbonate) is a strong alkaline and mild abrasive. It’s great for scrubbing, neutralizing odors, and dissolving grease so it’s water-soluble.

When combined, an exothermic reaction creates carbon dioxide which makes the concoction foam for extra cleaning power. That reaction and all of the foaming make this combination a very effective and versatile household cleaner.

Is it safe to mix baking soda and hydrogen peroxide?

The short answer is Yes. The resulting reaction is mild and releases a minor amount of carbon dioxide gasses. As the gasses release, the mixture neutralizes and can be easily washed away with water.

One note of caution. NEVER store the mixture in a closed container. The carbon dioxide gasses will build pressure inside the container and eventually cause it to burst open and spray everywhere.

For the reasons above, you should only mix as much as you can use at one time.

What Can You Clean with Hydrogen Peroxide and Baking Soda?

Due to its antibacterial, bleaching, and grease-busting cleaning powers, the duo can be used to effectively clean most household messes. It’s particularly effective on tough, protein-based messes, and is a great addition to your regular cleaning routine.

Degrease Sheet Pans

Are your sheet pans brown and sticky even after you wash them in hot water? That’s grease starting to bake onto the surface.

Rescue sheet pans by covering with a thick paste of baking soda and hydrogen peroxide. Let the mixture sit for 10 to 15 minutes.

If it has started to dry out, spritz with a little peroxide to moisten. Scrub with a scrubby sponge. Rinse under hot running water, and dry.

If your pans are completely covered, run them under hot water for a few minutes before applying the mixture. This will heat the greasy mess and help the mixture to penetrate and dissolve the grease.

Brighten Dingy Grout

Clean and lighten your dirty grout by applying a thin mixture of peroxide and baking soda along the grout lines. If you’re working with vertical surfaces, thicken the mixture a bit so it stays put.

Let the mixture work its magic for 15 to 20 minutes. Scrub the grout with a stiff bristle grout brush.

Wipe clean with damp sponge to remove all traces of baking soda. Let dry. Super grungy grout may need a couple cleaning session.

Pro Tip: Once the grout is dry, apply a good sealer to protect it. Clean and reseal once a year to make cleaning super easy.

Remove Cooked on Grease From Non Ceramic Pots and Pans

Are the cooked on grease drips and spots on the outside of your pans driving you crazy? Make them disappear with peroxide and baking soda.

Rinse the outsides of the pans with hot water to soften the cooked-on mess. Cover with a paste of baking soda and peroxide. Let sit for 15 to 10 minutes.

Scrub with a scrubby sponge and rinse under running water.

Knock Out Soap Scum

Soap scum is a pain and if you’re using bar soap, it’s building up quicker than you can remove it.

Blast soap scum by scrubbing with a stiff scrub brush and a paste of hydrogen peroxide and baking soda.

I pre-treat by spraying walls with hydrogen peroxide. Let it sit for 10 minutes, then use a clumpier paste and scrubby sponge to clean the shower walls and floor.

Rinse and let air dry.

Descale Your Faucets

You’ve probably heard of using vinegar to descale the buildup around your faucets. I stay away from vinegar because it damages so many surfaces.

Instead,try the baking soda and hydrogen peroxide cleaner.

Spritz the scale with a little hydrogen peroxide. Mix a paste of hydrogen peroxide and baking soda. Apply the mixture to the buildup until it’s completely covered.

Cover the area with plastic wrap and let it sit for 15 to 20 minutes. Remove the plastic wrap and scrub the scale with a stiff-bristled grout brush until it’s gone.

Once dry, rub the area with wax paper or auto wax to slow the scale buildup.

Blast Through Burnt on Food

Think you ruined your favorite pot by scorching the clam chowder? Don’t throw it out just yet.

Use a nylon scraper to remove as much of the mess as possible. Spray the bottom of the pan with enough hydrogen peroxide to completely cover the burnt-on mess.

Sprinkle baking soda to cover the same area. Let sit for 25-30 minutes.

If the baking soda appears to be drying out, spritz with more peroxide. When time is up, scrape with the nylon scraper again, then scrub with a scrubby sponge to remove the mess.

Clean Hard Water Build-Up off of Non-Metal Utensils

Have you noticed any cloudy white smudges or smears on your nylon, plastic, or silicone utensils? These are mineral deposits from hard water. They’re harmless, but unsightly.

To remove, create a paste of hydrogen peroxide and baking soda. Dip a damp microfiber cloth in the mixture and scrub the cloudy spots until they’re gone. Rinse and dry.

Hand wash and dry your utensils to prevent the buildup from returning.

Remove Laundry Stains

Are you still battling nasty sweat stains, deodorant buildup, grease stains and blood on your laundry? Hydrogen peroxide to the rescue.

Mix a paste of baking soda and peroxide. Place a small amount of the paste on the stain, then use a toothbrush or nail brush to scrub the area for a few minutes.

Rinse the area, then launder as usual.

Caution: test colored fabrics in an inconspicuous spot as hydrogen peroxide can cause bleaching.

Disinfect Water Bottles

Need to clean the inside of your water bottle? Hydrogen peroxide and baking soda have you covered.

Fill the bottle 1/4 full with hydrogen peroxide, then sprinkle in a few teaspoons of baking soda.

Put the lid on briefly to agitate the mixture. Gently roll the bottle back and forth to coat the entire interior with the solution.

Open the spout on the lit to slowly release the gasses, then remove the lid. Do not leave the lid on the bottle because the gasses will build up and cause excess pressure.

Let the bottle and lid sit for 10 to 15 minutes. Rinse and let air dry.

The peroxide will kill any bacteria, and the baking soda helps ‘scrub’ the interior surfaces.

Mixing Baking Soda and Hydrogen Peroxide

Depending on the application, you’ll want to control how thick or thin your mixture is.

Clumpy mixes (think blue cheese crumbles) work best when you need extra scouring power. I use a clumpier mix for tackling soap scum and cleaning hard water stains off of non-metal utensils.

A thick but runny mix (think molasses or old paint) works best when you need it to spread and stick to vertical surfaces. You should be able to put the thicker mixture on vertical surfaces and some of it will run down, but some will also stick and stay in place.

I use runny mixes for descaling my faucets and removing the cooked on grease from the outside of my pans.

The thin, runny mix (think syrup) works best for flat surfaces that can contain the spread. If you run your finger through the biddle of the mixture, it should quickly fill back in and cover that bare spot.

I use the thin mixture for baking sheets and the initial soak on burnt on food, then I add baking soda to thicken it up for extra scrubbing power.

There are many factors that can change how your mixture reacts including how clumpy your baking soda is, and how old your peroxide is.

Mix Ratios for Cleaning

Here are some mix ratios to get you started, and how to fix them if they aren’t quite right.

  • Clumpy – 3 parts baking soda to 1 part hydrogen peroxide
  • Thick – 2.5 parts baking soda to 1 part hydrogen peroxide
  • Thin – 1 part baking soda to 1 part hydrogen peroxide

If the mixture is too runny for your application, slowly add baking soda and mix thoroughly. If it’s too thick or clumpy add peroxide. I use my spray bottle when adding peroxide so I don’t ‘overpour’.
