It may be just an ingredient that you have in the kitchen, but after reading this, you’ll think of it as so much more. Bicarbonate of soda is a powerful, natural cleaning tool that really does make itself useful in almost every room of your home.

After experimenting with this chemical compound for a while, I’m here to share my personal experience and give you a helping hand. In this detailed guide, you will find out more about what it is, why it is so efficient to use as a cleaning product, and how exactly you can use it to treat your carpets.

Why Use Baking Soda On The Carpet

Baking soda is not simply a regular household ingredient that you keep in the back of your cupboard. This amazing compound can do so much good all over your house, in every room. Today I’ll let you know all my secrets about how to clean your carpet with baking soda, and why to use exactly this product from the wide range of cleaning substances available on the market.

Why Use Baking Soda On The Carpet

Below, I have shared some of the biggest pros of why you can and should use it on your carpet, as well as some cons that you’ll need to keep in mind:


  1. This is a multi-purpose product that you can use in all the rooms of your home. Even if you buy a huge package, I promise it will always be handy in one way or another. Bicarbonate of soda is a great solution for use in your kitchen, bathroom, living room, laundry, and pool, both to clean and to deodorize.
  2. In my opinion, the biggest pro of this compound is that it’s a natural one. Staying away from harsh chemicals and toxins is the best way to ensure the safety of your whole family as well as the integrity of your carpeting. Pregnant women, people with allergies, and those with skin conditions don’t have to worry about working with baking soda around the house.
  3. The best thing about bicarbonate of soda is that you can feel safe using it around kids and pets. Since this is a natural compound that people actually digest, it’s safe to say that you can also use it on the carpets while you have children and pets in your home.
  4. It’s one of the cheapest cleaning products on the market. You can buy a big bag and it will still be less expensive than other chemical cleaners. It is highly affordable and can serve many household purposes.
  5. Bicarbonate of soda is not irritating to the eyes or your skin. All chemical products can be very harsh, and that’s one reason why this is a superior alternative.
  6. This is not a joke: baking soda removes stains from carpets. It’s something that I’ve done for a while, and millions of other homeowners have done it too.
  7. It can neutralize bad odors and freshen up the look of your carpet.


There aren’t many cons when it comes to using baking soda in your home, especially when you’re using it to clean carpets. The few cons pertain to the stains and odors that this substance can’t fix.

  1. Let’s start with the unfortunate con that baking soda won’t completely remove old, stubborn stains. If this is a mess that you made a while ago, but didn’t feel like cleaning back then, bicarbonate soda won’t always do the job.
  2. Silk carpets are very delicate and should not be cared for using baking soda. Leave these carpets to be taken care of by professionals.
  3. If you use too much baking soda on your carpet, it can end up in your floor gaps or slab. That’s when things can get complicated, and you’ll find it very difficult to remove it from those narrow areas. This is one reason why I always recommend that you refrain from applying very generous amounts of bicarbonate of soda when cleaning.
  4. The more serious a stain is, the less baking soda will do to fix it. For serious staining, you might want to turn to carpet stain removers. If you notice that bicarbonate of soda is not doing anything, try a stronger alternative.

How To Prepare The Carpet

Before you actually start cleaning the carpet, you need to prepare it and gather all the necessary supplies. These are the things you need to have handy:

  • Baking soda
  • Vacuum cleaner
  • Spray bottle
  • Sponge
  • Old rags or paper towels
  • Hot water
  • Dish soap

The first step to prepare your carpet is to vacuum it. This will make things much easier for you because you’ll avoid developing additional stains that come from dirt already trapped in your carpet.

How To Prepare The Carpet

Grab your vacuum cleaner and go over the carpet. It doesn’t have to be the most thorough job, but make sure that you’ve cleared all the big particles, dust, and dirt. If by chance you miss this step, applying water directly to the stain can lead to new, deeper stains you’ll also need to address.

The best way to tackle a stain on your carpet is to act right away. The longer you wait, the harder it will be to remove later.

When you have a liquid mess to deal with, get a paper towel right away and blot it gently to remove the fluids. Don’t rub– this can just spread the fluid around and cause the carpet fibers to absorb the liquid faster.

Before you continue, let your family know where you’ll be using baking soda for carpet stains so that they can avoid these areas of the room. This is a natural product, however, it’s best if you can take the kids and pets to another room.

Reduce the traffic on the carpet that you’ll be cleaning, and be sure to avoid stepping where you apply the products. Now you’re ready to start!

3 Ways To Treat Carpets With Baking Soda

1. Cleaning Greasy Stains

Greasy stains are unfortunately hard to remove. They become more stubborn as the time goes by.

I’ve divided it the process into steps that are easy to follow and won’t take too much of your time:

Step 1: Use your sponge or a wet rag to soak the greasy stain with warm water. Be gentle, since you don’t want to push the stain further down into the carpet. Only dab and blot, never rub.

3 Ways To Treat Carpets With Baking Soda

Step 2: Greasy stains require more baking soda than non-greasy stains. I recommend more generous use of the product when treating greasy stains.

There is no right or wrong amount, but you should apply a thick layer only on top of the stain, covering it from all sides. It usually takes three to four tablespoons for medium-sized stains.

Also, though there is no designated time window, it’s best if you can leave the baking soda on the carpet overnight. When this is not an option, leave it for at least four to six hours.

Step 3: Vacuum the spot, removing all the remaining bicarbonate of soda. When you’re done, check whether the stain is completely gone, or you’ll need to go over the process again. Grease stains can be stubborn, so don’t hesitate to use baking soda more than once.

One of the tricks you can use to dissolve grease faster is to dab a little dish soap with warm water. Clean the spot with a rag, then continue adding baking soda.

Step 4: If the carpet is still damp after vacuuming, let it air dry or use a fan.

2. Cleaning Non-Greasy Stains

Non-greasy stains are much simpler and easier to remove, especially if they are fresh. After you’ve prepared the carpet according to the guide above, you’re ready to tackle those stains. Just follow the steps below, and your carpet will be as good as new.

Step 1: Start by locating the stain and applying baking soda on top of it. Make sure that you use a thick layer, but don’t overdo it. There is no need to cover parts of the carpet outside of the stain.

Step 2: Grab your spray bottle with hot water and spray it on top of the baking soda. Once again, there is no need to mist beyond the stain on the carpet. You can combine this with step one, by simply mixing the baking soda and hot water in the bottle ahead-of-time.

Step 3: Now the waiting can begin. This is the part when you can leave the room and get back to your regularly scheduled program. Leaving the mixture of soda and water on the carpet overnight is the best option, but if that doesn’t work for you, make sure that you leave it for at least three to six hours.

I highly recommend that you do this whole process before going to bed, and let baking soda work its magic overnight. That way you’ll skip the waiting and finish the job in the morning.

Step 4: When time is up, run the vacuum cleaner over the stain. It will remove the baking soda and leave the spot clean and fresh. This time, make sure that you vacuum thoroughly, completely removing the soda from the fibers.

If you notice that the stain is not completely gone, you need to repeat the process. It’s something that happens with stubborn stains and those that have been there for a while.

3. Removing Pet Odor

Odor and hair don’t exactly fall into the regular stain category, but are still issues that can be treated with baking soda. Only pet owners will understand how difficult it is to remove this kind of odor from carpets. This deodorizing method is basic, but efficient.

Step 1: After vacuuming the carpet well, apply baking soda to the portions where there is an unpleasant odor. Let the soda work for at least three hours. If you can, leave it on the carpet overnight.

Step 2: Get the vacuum again, and go over the entire carpet, making sure that you’ve removed all the baking soda. After you’re done, check whether the smell persists. If it does, go over the process once again.

This is one of the easiest and most natural solutions when it comes to dealing with pet odor. It’s not harmful to pets, and you can feel safe doing it as often as needed.

FAQs About Baking Soda As A Carpet Cleaner

Is Baking Soda Good For Carpet Stains?

Bicarbonate of soda is one of the best household products you can use to remove carpet stains. The secret here is simple: this is a natural alkaline product that really targets stains and odors, especially if they are fresh.

Baking soda will not cause any harm to your carpet. On the contrary, many people use it to refresh their carpets and make them look new. Be careful if yours is made of silk fibers, as this is a much more delicate material that requires special care.

How Does Baking Soda Remove Stains From The Carpet?

Bicarbonate of soda is a mildly alkaline chemical compound that dissolves in water and targets dirt, grease, dust, odor. When mixed with hot water, it releases a gas that helps remove stains.

It’s also slightly abrasive, and that’s how it removes dirt and particles from fibers effectively. At the same time, baking soda neutralizes unpleasant smells, a reason why many homeowners use it to eliminate odors caused by pets.

Can I Mix Baking Soda With Other Ingredients?

Yes, you can mix baking soda with other ingredients. At the same time, there are chemicals you want to completely avoid when you’re cleaning with this compound.

Some substances you can safely mix it with include dish soap, lemon, and water. Stay away from bleach, hydrogen peroxide, vinegar, ammonia, and similar chemical compounds when you’re working with baking soda.

How Long Do You Leave Baking Soda On Your Carpet For?

The longer you leave it on the carpet, the more effective it is in doing the job. When your goal is to remove stains, leave it on for at least three hours for non-greasy stains, and at least four hours for greasy stains. If you’re trying to deodorize the carpet, an hour can do the job, but I still recommend that you leave it overnight for all these purposes if you are able to.

What Does Baking Soda Do To My Carpet?

Baking soda can remove stains, deodorize your carpet, and freshen up the appearance of a room. The good news is that it can target both greasy and non-greasy stains, and the sooner you act, the better. Another positive effect is that it deodorizes and neutralizes unpleasant smells.

Will Baking Soda Bleach My Carpet?

Baking soda will not bleach your carpet. Although it may leave a white residue, after vacuuming the carpet thoroughly, it should be completely gone. It should remove marks and stains.

Can Baking Soda Be Harmful To My Health?

The reason why so many people use baking soda to clean is that it’s safe to use. If you properly use it to remove stains from the carpets, you shouldn’t worry.

Although it’s also safe to use around kids and pets, it’s better that you keep them away from the carpet while baking soda is working its magic. Even if your pet eats it by mistake, it’s not harmful unless consumed in very large amounts.

This is a natural product that is very gentle, so the chances of harm are extremely low. Many household cleaners contain harsh chemicals; this is a much safer option.

Be sure to apply a thick layer that will cover the stain and/or fight its smell. Store the rest carefully in a cabinet that is out of reach for kids and pets.

Can I use baking soda in my carpet cleaner?

There is no need to mix baking soda with your carpet cleaner. Carpet cleaning solutions are made to remove stains effectively, so you should either use baking soda or a store-bought cleaner.

If you want to avoid using chemicals on your carpets, you can just opt for baking soda or find a DIY recipe online that will use baking soda, among other natural ingredients. If you don’t mind using a carpet cleaner, it’s best that you use it first, then use the baking soda afterwards to neutralize smells and provide a deep clean.

Is baking soda good for carpet cleaning?

Yes, bicarbonate of soda is a great carpet cleaning compound. It’s an alkaline chemical compound that you can use to refresh carpets, eliminate odors, remove non-greasy stains, and in most cases, greasy stains. However, baking soda might not be as successful in removing old, stubborn stains that have been on your carpets for a while.
This chemical is one of the most natural ways to treat your carpets and has the ability to dissolve in water and target dirt particles. When it comes into contact with hot water, bicarbonate of soda lifts stains and dirt up from the carpet fibers.

What happens if you leave baking soda on the carpet?

If you leave baking soda on your carpet for a very long time, it will leave a residue on the fibers. In general, it’s recommended that you treat your carpets with soda overnight, then thoroughly remove the powder with a vacuum cleaner. Using too much soda or leaving it too long will make it very hard to remove from the carpet fibers.

How do I use baking soda to deep clean my carpet?

If you want to clean your carpets with bicarbonate of soda thoroughly, you need warm water, a clean cloth/sponge/rag, and a generous amount of baking soda. If there are any stains, you should target them first, then apply a thick layer of soda on top of the entire carpet.
Let the compound work on the carpet overnight or for up to 24 hours. Then you can vacuum it to remove it and check whether the stains are gone. If not, you can repeat the process all over again
