Can You Mix OxiClean and Baking Soda? (Yes, Here’s How)

Combining some cleaning products, no matter how non-toxic they may be, is not a good idea as some combinations can be downright hazardous and potentially fatal!

However, you can mix OxiClean and baking soda to create a safe, potent cleaning solution. OxiClean’s active ingredients and baking soda are made of very similar compounds. And because both products are alkaline, the two can safely complement each other when combined.

Let’s explore why you’d want to combine OxiClean and baking soda, how to mix the two to remove pesky stains, and what products you never want to mix with OxiClean.

Why Mix OxiClean and Baking Soda? 

While OxiClean and baking soda can each brighten colors, remove tough stains, soften water, and deodorize on their own, the two alkaline products can be safely combined for an effective cleaning solution.

OxiClean’s ingredients include sodium percarbonate (Na2CO3·H2O2), sodium carbonate (Na2CO3), surfactants, polymers, and other unknown ingredients.  

When OxiClean is dissolved in water, its main ingredient, sodium percarbonate, breaks down into its components, sodium carbonate (Na2CO3) and hydrogen peroxide (H2O2).

Combining baking soda, also known as sodium bicarbonate (NaHCO3), an alkali molecule, with hydrogen peroxide, a weak base, creates an exothermic reaction that generates heat and carbon dioxide gases. 

The resulting reaction easily and safely breaks apart and removes grease and organic stain molecules from a variety of surfaces.

Together, OxiClean and baking soda make an effective yet gentle cleaner that can tackle stubborn stains like blood, grease, dirt, and grime.

How to Mix OxiClean and Baking Soda

In the past, I’ve always used OxiClean and baking soda separately, with the extent of my baking soda use being limited to deodorizing my refrigerator and baking.

However, to my delight, there are several ways you can safely mix OxiClean and baking soda for a versatile, effective cleaner. 

Here are a few approaches to using the two products together.

In the Laundry Room


To remove stubborn stains from textiles, such as blood, grass, food spills, makeup, sweat, or grease, make the following pre-treatment paste:

If using powder OxiClean, make a solution by mixing up to ¼ scoop with 16 ounces of water. Then, mix a small amount of baking soda with enough OxiClean solution to make a paste.

To pre-treat difficult stains, like yellow sweat stains on white garments or stubborn grease stains, I like to heat the water until it boils. 

I let it cool down just a bit, and then I add OxiClean. It will bubble right away, so be careful – I advise you to do this in the sink or the bathtub. 

Apply the paste to the stained area, allow to sit for up to 10 minutes, and rinse. Do not allow the paste to dry on the fabric.

Wash with detergent as normal.

If using liquid OxiClean, combine enough of it with baking soda to create a paste. Follow the same instructions as above.

Be sure to test a small area before applying it to the entire garment or to a visible area as the combination may not be suitable for all surfaces or textiles.

You can also use OxiClean and baking soda separately but in the same wash.

For example, you can use OxiClean to pre-treat a stubborn stain, wash with detergent as normal, and then add about ½ cup of baking soda during the rinse cycle as a fabric softener or odor remover.

As an Acid Neutralizer

To neutralize and clean acid stains, such as drain cleaner, battery acid, toilet bowl cleaner, vomit, or urine, rinse the area with water and sprinkle baking soda to prevent further damage to the surface. Allow it to sit for a few minutes.

Then, scrub the area with an OxiClean and water solution. Pat excess liquid away and allow to air dry.

If possible, vacuum the area when dry. Otherwise, wash in the laundry as usual.

As Grout Cleaner and Soap Scum Remover

The mild bleaching action of the hydrogen peroxide released when OxiClean is dissolved in water, along with the gentle abrasiveness of baking soda makes a great grout cleaner.

Simply mix the OxiClean-water solution with a small amount of baking soda until it forms a paste.

Apply it to the grout and let it work for at least 10 minutes. Then, use a grout brush or an old toothbrush to scrub the grout lines.

Wipe away the mixture with a damp sponge or cloth and rinse with clean water.

Fiberglass tubs and showers can accumulate a lot of soap scum. However, harsh cleaners and abrasive cleaning pads and brushes can be very damaging to the material.

To clean soap scum off fiberglass, make an OxiClean solution and baking soda paste. Apply it to the area with a sponge and allow it to sit for about 30 minutes.

Scrub using a non-abrasive sponge or brush from top to bottom. Rinse well and dry with a towel to avoid water spots.

Things to Never Mix with OxiClean

While OxiClean is a versatile cleaner and mild alkali (pH 9-10), it can be dangerous to mix with other products.

To avoid potentially hazardous reactions, DO NOT mix OxiClean with the following products:

  • Bleach – It can produce chlorine gas, a toxic and potentially fatal chemical.
  • Vinegar – This acid can react with OxiClean’s pH, decreasing the mixture’s cleaning power. More importantly, the hydrogen peroxide released when OxiClean mixes with water can react with vinegar to produce peracetic gas, a highly corrosive and toxic chemical.
  • Ammonia – It produces toxic fumes.
  • Other Household Products – Can produce toxic chemical reactions with a variety of ingredients and formulations.

To Wrap Up

Because OxiClean and baking soda are both basic, they can be safely mixed to complement each other, creating an effective cleaning solution.
