Baking soda is a chemical powder that bonds with a wide range of compounds and neutralizes foul odors.

We’re here to give you a brief explanation of how to use baking soda on the carpet.

What Stains Can Baking Soda Clean?

stains baking soda can cleanBaking soda works well in cleaning a variety of stains. Some of the most common are:

  • Blood
  • Urine
  • Ink
  • Grass
  • Vomit
  • Dirt
  • Grease
  • Wine

Baking soda’s chemical properties enable it to form a bond with just about any substance, making stains easier to remove as a result.

When the stain gets neutralized with the proper application of baking soda, it is far easier to remove because it’s no longer bound to the carpet.

You may have to use water or vinegar as an aid, depending on what kind of stain you have. Organic messes respond best to baking soda since things like urine are primarily acid-based.

Powder vs. Mixture

Creating a paste of water and baking soda lets the cleaning solution make its way deeper into the carpet fibers.

You can also use white vinegar as a solvent. It creates a foam that lifts stubborn stains and isn’t difficult to remove.

Generally, two broad types of stains exist: greasy and non-greasy.

Greasy stains are the ones that have a moist, underlying residue. To get these stains out of the carpet, you first need to blot the area dry with a paper towel and sprinkle dry baking soda on it for a few hours.

Non-greasy stains lack this residue. To make baking soda effective for these kinds of stains, sprinkle it on top, then pour hot water. Heat loosens molecules that have bonded together and allows stains to come up more easily with the vacuum cleaner. For best results with this method, leave the baking soda on overnight.

How to Apply Baking Soda

The sooner you get to your carpet stain with baking soda, the more successful you’ll be at cleaning up. First, if it’s a liquid stain, you should use paper towels to blot up as much of it as you can. Then, sprinkle baking soda over the area and allow it to work over the course of half an hour. Deeper stains may take longer.

Don’t leave this on the carpet for more than a day. Baking soda is a great cleansing agent, but it can leave stains if you aren’t diligent about removal.

To remove, you should use a vacuum cleaner. You probably will need to change the bag and filter afterward, depending on how much baking soda you put down. Set your vacuum cleaner to the lowest height possible.

Other Tips for Cleaning Your Carpet

Baking soda removes odors in a room and carpet.

Treating your carpet regularly with baking soda can do wonders for the carpet’s freshness and appearance.

Once every two weeks or whenever you change your vacuum cleaner bag, try sprinkling some baking soda inside the bag.

You can also add other scents to the mix if you want a specific smell. Walking into a room whose carpet smells of fresh cinnamon, for example, can make guests feel particularly welcome.

Also, if you have a dark-colored carpet, be aware that baking soda might leave a discolored patch.

For tougher stains consider using a home carpet cleaner. We recently did a post with carpet cleaner reviews of the top machines of 2021.

So Why is Baking Soda Effective in the First Place?

This property makes baking soda useful when placed on carpet stains because it makes them more able to be dissolved in hot water. Water itself is known as the universal solvent, but a little baking soda helps as well.

Baking soda also has abrasive properties. Putting a little of it on a scrub brush can make the scrub brush more effective than it would be otherwise.

Finally, baking soda is made of non-toxic chemicals, unlike many commercial cleaners. Baking soda is sodium bicarbonate, a mineral compound occurring frequently in nature.


Keeping a few boxes of baking soda around does more than making your fridge smell great or help with baking.

Baking soda makes a fantastic carpet cleaning tool because of its ease of use and chemical versatility. Just make sure to clean up the baking soda used on carpet afterwards. Otherwise, it might leave a mark on your carpet.
