You can eliminate almost any mattress stain and odor using a vacuum cleaner and ingredients found in your kitchen or medicine cabinet.
Every night, you shed dead skin cells that sift through your sheets and wind up on your mattress. So do the dust mites that feed on those skin cells. Some mattresses grow mold and mildew, too, especially if you sweat a lot in your sleep or live in a humid area. A dirty mattress makes your symptoms worse if you have allergies or asthma. And, of course, old mattresses smell bad, while stained mattresses are embarrassing.
Deep-Clean Your Mattress in 6 Steps
The good news is that you can easily get your mattress looking new again. Follow the steps below to deep clean your mattress and get rid of odors and stains, then check out my tips to protect your mattress and keep it in like-new condition for years.
Step 1: Gather Supplies
You only need a vacuum with attachments, baking soda, hydrogen peroxide, mild dish soap, table salt, and some microfiber cloths to remove most stains, bacteria, and odors from your mattress.
Step 2. Remove Your Bedding
Take off all sheets and blankets from your bed before you start cleaning your mattress. This is a great time to launder them. Use the hottest laundry temperatures allowed on the manufacturer’s labels to kill dust mites. Go ahead and wash your pillows and fabric mattress toppers, too. You can even launder electric blankets.
Step 3: Deodorize Your Mattress
Avoid cleaning your mattress with commercial products with a strong fragrance or chemical smell, since those will become overpowering when you’re actually in your bed. They can also make allergies and asthma worse. It’s best to use plain baking soda to deodorize your mattress. Sprinkle a light layer of it on your mattress and rub it in with your hand. Avoid scrubbing with a brush, since it can snag the surface of your mattress. Let it sit in place for at least 15 minutes to bond with surface moisture — the longer the better.
Step 4: Vacuum It
Use your vacuum cleaner’s dusting brush or upholstery attachment for this step, since a rolling brush may snag or damage the mattress surface. Clean the top and sides of your mattress in overlapping, narrow paths, including near the seams and edges where dead skin cells, debris, and dust collect. To make sure you’re removing all of the baking soda, work from the top of your mattress toward the foot, then turn and go over the mattress surface from one edge to the other.

Step 5: Remove Mattress Stains
You can eliminate almost any mattress stain using ingredients found in your kitchen or medicine cabinet. Before you start, there are a few things to keep in mind.
- Never pour anything directly onto your mattress. Mattresses aren’t meant to get wet and will grow mold inside if they do, especially memory foam mattresses which are basically giant sponges.
- Do not use a carpet shampooer to clean your mattress. These machines do not extract all moisture, so the excess liquid will turn into hidden mold and mildew.
- Treat all mattress stains of one type before tackling the next kind. Since you should never mix cleaning products, even natural cleaners, treat all stains of one kind and let them dry before treating the next type.
Sweat Stain Remover
If your mattress is yellowed from sweat stains, or you feel like it’s looking dingy, lightly spray the yellowed area with 3% hydrogen peroxide until it’s damp but not soaking wet. You can usually put a clean spray bottle nozzle directly onto the peroxide bottle. The stain will fade as the peroxide air dries. Repeat as needed.
Blood Stain Remover
You can get blood stains off of your mattress and other fabrics so long as you haven’t used any treatments involving heat, which can make them set permanently. This formula gets fresh or old blood stains out of your mattress.
Combine 2 ounces of hydrogen peroxide and 1 tablespoon each of liquid dish soap and salt. Spread this on the bloodstain and wait 10 minutes, then scrape it away with a spoon. Use a clean rag dipped in hydrogen peroxide to remove any residue. Let the area dry. If a brown discoloration remains after drying, spray it lightly with hydrogen peroxide. The stain will fade as the peroxide dries.
Urine Stain Remover
To remove fresh or old urine stains on your mattress, and also their odors, combine 3 tablespoons of baking soda, 8 ounces of hydrogen peroxide, and a tiny amount of liquid dish soap in a bowl. Use a rag to dab the mixture onto the stain, but don’t drench it. Switch to a clean cloth and blot the moisture. Turn your rag as you work, so you’re always using a fresh spot to lift the stain. Once it’s gone, go over the area with a cloth dampened in cold water then let it air dry.
Wine, Vomit, and Other Stubborn Stains
Use this cleaning solution to remove wine spills, vomit, other bodily fluids, and unknown mattress stains. Whisk 2 tablespoons of powdered white laundry detergent (no blue crystals, no oxygenated bleach) with 1 tablespoon of cold water to create a dry foam. Spread the foam on the stain, wait 10 minutes but do not let it dry, and scrape it away. Spray the area with hydrogen peroxide to loosen any stubborn residue, then wipe the rest away with a damp rag. Let it air dry.
Alternatively, you can sprinkle more baking soda on the spot and work it in with your fingers, then spray the area with white vinegar. This will cause a foaming reaction that may dissolve the stain’s bonds to your mattress fabric. Once the foaming subsides, wipe the area with damp paper towels or a cloth and let it air dry. The scent of the vinegar will disappear as it dries.
Step 6: Flip and Repeat
Once your mattress is clean and dry on the top, you may want to flip it and clean the underside. If one side has a pillow-top and the other doesn’t, the flat side of your mattress probably won’t need stain treatment. You should still vacuum it, though, especially if you have allergies or pets that like to crawl under your bed.
How to Keep Your Mattress Like New
Once you’ve removed all the stains and odors from your mattress, you can keep it fresh by simply using a mattress protector, not just a fitted sheet. Look for one that provides hypoallergenic, waterproof protection. Here’s the one I use. With a waterproof protector, you’ll never have to worry about mattress stains again.
Place the mattress cover over your mattress and then add your fitted sheet. If you use a foam topper or mattress pad to make your bed softer, put it on top of the mattress cover then add your fitted sheet. Wash your mattress cover monthly to keep it fresh, and let your mattress air out while it’s in the washer. Fresh air and sunshine are two great ways to eliminate mattress odors, even hidden mold.
Common Questions About Mattress Cleaning
Below are some frequently asked questions about cleaning mattresses.
How Often Should I Clean My Mattress?
Without a mattress protector, you’ll need to vacuum your mattress monthly to remove dust mites, dead skin cells, and surface allergens. Treat any stains at that time, and deep clean it twice a year. With a mattress protector, you just need to let your mattress air out while the protector is in the washing machine.
How Often Should I Flip or Rotate My Mattress?
Flip or rotate your mattress every three months. If your mattress is the same on both sides, flip it one time and rotate it the next. If your mattress has only one side for sleeping, rotate it end to end every three months. This habit will help prevent saggy spots and lumps, and prolong the life of your mattress.
Can I Use a Carpet Shampooer or Steam Cleaner on My Mattress?
No. A steam cleaner pushes water deep into your mattress where air and light don’t reach. Your mattress is basically a big, thick sponge. Imagine the smell of a wet sponge left in a dark, warm spot for a few days. Moisture inside your mattress may also lead to mold and mildew, too.
Can I Use Essential Oils to Freshen My Mattress?
No. Essential oils will void most mattress manufacturer warranties. That’s because essential oils smell nice, but they are still oils. Rubbing oil into fabric attracts dirt, which can become a permanent stain. Also, by the time you’ve vacuumed and covered your mattress to protect it, you won’t smell the essential oil. So why waste time and effort?

The tip for getting urine stain out has worked a gem although I buy premixed washing detergent not powder so didnt get a foam but still smells nice
I tried the hydrogen peroxide and baking soda mixture to get those awful brown stains off an expensive king mattress. Worked like magic. At first I thought it wasn’t working but when I looked a half hour or so later the stains were gone! Be patient. More is not always better in this case.
Glad to have helped, Beth!
Will that also work on a yellow stain in a mattress? Deep cleaning my room before I leave for Christmas vacation and I got my bed from my sister but I’ve notice it got a yellow stain on it.. but will that also work on it? Practically a brand new bed, didn’t use it for a long period of time before she gave it to me. Thank you
Most yellowing stains are either from sweat or urine. I’ve provided recipes to remove both types of mattress stains.
I looked at your website too late. I have already soaked my mattress with bleach and used the steam cleaner on it.obviously that didn’t work very well otherwise I wouldn’t have started looking for your site. I hope to let it dry and then perhaps try one of your methods. I have a urine stain on my bed from my old dog who had kidney problems. scrubbing it with bleach and the steam cleaner only made a big white spot where the urine was and the rest of the mattress is the color of when I bought it. I think I’ve made a mess and this is an expensive mattress. I wish I would have come here first. Wish me luck!
Oh no! Soaking a mattress is never, ever a good idea. But here’s some bad news: if it’s soaked, it’s going to take a very long time to get it completely dry. Blot as well as you can with towels (seriously, put them on and lay down on them, then switch to new ones, repeat, etc. until the towels come up dry) THEN let it air dry or blow a fan at it for a day or so.
After it’s completely dry, give my methods a shot. But don’t soak it — never soak it. Please.
I hope it all works out for you! My dog did the same thing when she was having kidney and liver issues, bless her heart, and the directions in this blog entry fixed it. Wish I had directions to bring her back. She was a very good dog.
Katie your tip for stain worked great. My four year old did a number on my mattress which sift through the mattress cover I had (I ought to think about changing that) and the rest of the solution worked great for removing her pencil graffiti from the wall. Thanks!
Bebe, I’m so glad to have been of help! Thank you for taking the time to let me know. 🙂
Any suggestions if you don’t own a vacuum? I realize that sounds odd, but our house has all wood or tile floors. Our vacuum was old and not useful for sweeping those types of floors (unless I liked scratching up the wood!) so I gave it to a friend who needed one.
You could use a shop vac if you have one, or you could borrow one (vacuum or shop vac) from a family member or good friend or neighbor.
That’s great advice, Heather!
Thanks for the hydrogen peroxide/baking soda/dishwashing liquid cleaning tip. It worked wonders on my children’s mattresses which had a bit of everything stains( urine,sweat and blood due to my sons nosebleeds). Still trying to scrape off the paste which I also used in an attempt to extra clean one stubborn spot on the mattress
You’re welcome!
Would a little vinegar on a cloth help with the soap crust? Vinegar is my go*to.
Hello, just bought a brand new loom and leaf foam mattress. Blood stain, didn’t read this before i started cleaning it but what I did was use soap and cold water and it completely came out. Now there is a large brown ring surrounding the cleaned stain. How do I get that out?
The brown ring is where the soap and water spread the blood, rather than completely getting rid of it. Spraying hydrogen peroxide lightly on the ring should take it away after 15 minutes or so. Don’t drench the mattress; just spray lightly, wait, blot with a clean white cloth and repeat if necessary.
My 4 year old sister came to visit me earlier this year and she had an accident in my bed, i thought we’d cleaned it up but the pee stained, i just tried your hydrogen peroxide/baking soda/soap concoction.. and can I just say.. THANK YOU!!!!!!!!!!! I really appreciate the post, it’s helped me so much! 😀
I’m so happy to have helped!
Hi, I found a very large yellow stain on my mattress about 1 meter x 80cm…which I don’t remember being there before I stored it during my move. There is no odour. None of the mattress protectors have a stain. Its a puzzle. Anyway we sprayed it with white vinegar and then ladled bi-carbonate soda on it and left it overnight. Now just brushed a bit of the soda away…the yellow stain is till there 🙁 Question: is bi-carbonate soda the same as the baking soda you are talking about? I’m in the UK. I don’t use this soda in baking.
Can you help?
Yes, bi-carbonate soda is the same thing as baking soda. Hydrogen peroxide is really the key to removing that stain. You should be able to purchase it at the chemist.
That. Is. Awesome. Thank you for solving a lifelong struggle in one fell swoop!
Great. This works wonders!!! My jaw dropped to the ground then I dropped to my mattress!! Could not believe the difference. Thank you thank you thank you!
I’m glad you tried and liked it, Leah!
Hi, I recently recieved a mattress that has never been used but was stopped in a basement for a couple of years. It reaks of a musty molded basement! I have tried putting it outside to air out, then fanning it out inside after spraying it down with bleach, thinking would kill any mold present. The smell is still there! I don’t know what to do. Can you help?
Assuming it’s completely dry, I’d work baking soda into all surfaces of the mattress and let that sit overnight, then vacuum it very well using your machine’s upholstery attachment. If it still reeks after that, it’s probably hopeless. Sorry! 🙁
Will this work on urine stains that have been there for a while? I have made the mistake of using two mattress covers on my son’s mattress and did not think to look at the condition of the mattress, Well, today…I noticed a good sized urine stain from my son’s dog and I am not 100% sure how long it has been there. Help!
Yes, it works wonderfully on old stains!
Does it clean OLD and i mean old like 1 year old blood stains? Same goes for urine stains? Thank you
Yes.
Thank you very much, it worked!
I used it on my mattress about twenty-five minutes (25) ago and it really works. The stain has gone.
I’m so happy to have helped!
I have fake tan and night sweat stains on my mattress , it’s a spring coil mattress made with natural fibres and an attached pillow topper covered in damask material. These stains are old , can I get them out ?
Hi Julie,
I’m sorry that I don’t have any specific answers for this since it’s not a problem I’ve encountered. Everything I’ve found about removing fake tan from fabric suggests a combination of warm water and liquid dish detergent, or warm water and oxygenated bleach (like OxiClean). Obviously, you can’t saturate the top of your mattress but maybe try wiping the areas with this to remove the fake tan, then treating the sweat stains afterward?
You might also want to consider getting a waterproof, washable mattress pad, so you don’t have to do this regularly.
I have a mattress with water stains that are a bit old. Other than that the mattress is in excellent condition.
How can I remove the stains. Thanks
Hi Germaine,
I’d treat them as urine stains and use the methods described.
I have a extremely deep mattress and havnt bought the sheets to match …my labrador has been rubbing against the side of the bed and left an oily stain along it from his coat what would be the best method to get rid of it thanks
Hi Graeme,
A bit of liquid dish soap and warm water should remove oily stains. I’ve found that Dawn (in the US) or Fairy (in the UK) are the best at cutting through greasy residue.
Hi i came very late to visit your site..i washed my mattres 3 days ago with water and now its dry on both surface but the water is still present inside…its too heavy…i am very upset about it…i realized my blundder that it should be not wet…How can i dry it completly?? Kindly suggest
Hi Naila,
I’m sorry you hadn’t found my site before getting your mattress wet. I’d move it to a sunny spot outside and place it on something that keeps it off the ground. That way the air can circulate while sunlight helps it dry. If you have access to a shop vacuum (a wet/dry one) you can try suctioning the water out, too.
Any recommendations for white powder detergent? I don’t use powder and the ones I’ve used in the past all had the blue crystals.
Hi Amanda,
Most powdered detergents for sensitive skin don’t have blue crystals. I think Arm & Hammer’s powdered detergent doesn’t, either.
I have a brand new Sterns and Foster mattress and I noticed a small black spot almost looks like grease in one of the divots so I got out a white wash cloth and dreft baby soap with a little water and gently dapped and rubbed a little – the black spot is gone (yay) but now I am left with a white spot (mattress off white color) what should I do?
I’d just wipe the spot more. It sounds like there might be a little soap residue left since the Dreft doesn’t contain any bleach and your comment indicates the rest of the mattress is off-white.
Would the mixture for wine stains work on old coffee stains? Also, would you suggest doing the larger stains first before the other stains?
The wine stain solution should work, yes.
What about an overall dirty looking mattress? I think from moving in uhaul. Would the spraying of hydrogen peroxide clean it up?
It should definitely help.
Hello I try using the hydrogen peroxide dish soap and baking soda but I add the baking soda after the spray. Mattress looks way better but it still has some yellow stains do I keep doing the process until the yellow stains are gone and the Mattress feel rough not smooth how it use to be. How can I get the mattress to be soft again.
Hello! I’m not sure I understand what you mean about adding the baking soda after the spray. That said, roughness is a sign there’s still baking soda on your mattress. Vacuum it well using the upholstery attachment to get up any remaining baking soda. Then you can repeat steps as needed to finish removing any yellowing, but be sure not to drench your mattress in the process.
