Why Does Baking Soda To Clean Mattress Work?

If you're familiar with baking soda, you can pinpoint one or two great qualities of this agent. To be more realistic, there's much more to list than one or two. 

Soaking your mattress can cause moulds, stale smells and a longer time to dry, which is why baking soda is a cool way to treat your bed.

Baking soda is a deodorising agent that combines two superpowers to kick out dirt from your mattress. It takes away the odour and cleans stains without harming the fabric. This bicarbonate takes out moisture, dust, and any form of dirt.

How To Clean A Mattress With Baking Soda - Step By Step Process

Here's a guide on how to take care of your mattress using baking soda. It's easy and fast. Make sure you have your baking soda powder ready.

  • Clear your bed by removing pillows, duvets, bed covers etc. Just bare the mattress and wash up the linens and pillows.
  • Vacuum or sweep off any dirt on the mattress and clean up stains using detergents or spot cleaner
  • Depending on the size of your mattress, pour 1-3 cups of baking soda on the mattress. But ensure that all sides are covered, especially the dirtiest areas.
  • Expose the mattress to sunlight from your window or take it directly into the sun and allow it to absorb for 24 hours.
  • Then vacuum, and you would see and perceive the difference.

1. Gather Your Supplies

You may be super eager to get rid of that reek slowly coming from the mattress but being prepared will save a lot of time and prevent procrastination or disinterest.

Start the ball rolling by gathering your supplies. These are essentials you can find in the kitchen or buy from a nearby store.

Baking Soda

Baking soda, also known as sodium bicarbonate, is not just an ingredient sitting on the kitchen counter; it is a popular agent with DIYs. This fine white powder will send the odour away and clean up spots. 

To use your baking soda, the most important ingredient in this mix, you need one to three cups for an average bed. 

Essential Oils

One thing to love about mattress cleaning is the whiff of refreshing scents tangled with a fresh feel. Essential oils bring a pampering effect to your cleanup. 

And guess what? 

Tea tree and lemon essential oils will give a fresh and clean effect; lavender oil, which is highly antibacterial or peppermint oil, keeps the bugs away. 

Spray Bottle

Spray bottles will ease the application process and help you measure and mix your ingredients in a safe, covered container. A 500ml bottle will be enough, but this also depends on what you feel comfortable using. 

Another factor to consider is colour. A darker bottle will preserve the contents longer.

Bristle Brush

For a bit of scrub here and there, get a bristle brush. This is especially useful for stubborn stains and yellowish spots. A long bristle brush is easy to handle and easily glides over hidden areas.


Vinegar is also an ingredient easily found in the kitchen. It kills odour, and white vinegar is highly effective. This agent will help you clean off stains with ease. 

This is especially useful when you have urine or sweat build-up to clean.

Now that you have all you need, it's time to get into it.

2. Prepare the Mattress

Preparing your mattress is quite easy. First of all, remove all sheets, pillows and blankets. If you use bed covers, that has to go too. You need to bare the bed as you launder the items removed. Baring the mattress gives room for the ingredients to penetrate easily. 

3. Vacuum and Clean the Mattress

For the ingredients to penetrate, clean up the mattress by first of all vacuuming off any debris on it. Plug in the vacuum cleaner and go over the mattress. You can use a handheld vacuum or upholstery attachment. As you vacuum, don't forget the sides as well.

4. Spot Treat Your Mattress Area

 If the bed is occasionally messed up with urine stains, poured drinks, or sweat build, you may find a couple of stains on the bed. 

These stains may be yellowish depending on the composition. To spot treat, mix half of the vinegar and half of the water. 

Mix in a spray bottle and apply on the affected spots. Go in with a wet cloth and massage the area for a while. As a substitute, you can scrub affected areas using the bristle brush, which helps the cleaning agents go deeper and break particles and dirt buildup to give the best results.

5. Sprinkle Baking Soda

Now pour about one to three cups of baking soda all over the bed's surface, paying close attention to the stained spots. 

Add more amounts of soda in these areas. 

Leave the baking soda to settle in for a minimum of 1 hour and a maximum of 24 hours. The longer it stays, the better, especially if it has been unclean for a while or the stains are deep.

6. Use the Vacuum Again

After following the steps above judiciously, plug in your vacuum cleaner again and suck up the baking soda. Don't forget to go over the edges also.

7. Air Dry

Don't forget to open the windows. Good ventilation will not only dry it easily, but it will allow the mattress to smell clean and fresh. 

If you can access the sunlight, it's also beneficial to remove the smell of vinegar or any agent and make it difficult for any bugs or insects to survive.

How Often Should You Clean Mattress With Baking Soda?

How many times you indulge in taking care of your mattress is up to you. You determine how dirty it gets and how often you want to do it. Generally, you would clean your mattress topper more often than your mattress, depending on how dirty it gets.

Generally, a good clean thrice a year will guarantee the cleanliness of your mattress. No stains, moulds, or smell.

Tips To Keep Your Mattress Clean

Doing any form of cleaning can be tedious to the best of us. They say prevention is better than cure which is why these tips will keep your bed cleaner for longer.

  1. Change the sheets. If the stains and dirt build up on the sheets for a while, it affects the mattress next.
  2. Have a cleaning routine. You can choose to clean after every six months or three months.
  3. Vacuum. This will drag out dirt that may otherwise have gone unnoticed.
  4. Use mattress covers. These protect the mattress for longer.
  5. Flip the mattress quarterly. This extends wash time by a couple of months and gives a fresh feel as well.

Baking soda is highly efficient and effective in cleaning mattresses. Another advantage is how accessible it is and how affordable this method is. Baking soda has strong properties that make it a cleaning agent worth trying out.

2. How Long Do You Leave Baking Soda On Mattress?

How long you decide to leave the baking soda on your mattress largely depends on you. On average, you should leave it on for 30 minutes or more, enough time for the baking soda to be absorbed and remove dirt.

3. Does Baking Soda Remove Stains From Mattress?

Baking soda dissolves organic compounds such as dirt or grease. It also absorbs smells and dirt. It is especially more effective when mixed with vinegar which is also a strong agent. 

4. What Is Yellow Stain On Mattress?

Yellow stains result from oil, sweat or even urine on the mattress. This moisture creates yellow or mildew covering specific areas of the mattress. They are removable and should not be a cause for alarm.

5. How Can I Get My Mattress White Again?

One of the easiest and cheapest ways to get a clean, white mattress is to use vinegar and baking soda. Use a sponge or cloth to dab or wipe the affected areas. Another method is to use a cup of 3% hydrogen peroxide and three tablespoons of baking soda.
