How To Get Urine Smell Out Of Mattress

A detailed guide on how to clean urine out of a mattress, and make sure there is no smell left to linger.

In this post, we teach you how to properly get your mattress clean again after an accident with urine. We’ll help you to make sure everything is nice and sanitary, so you’re not left with a stain or any odor.

Whether it was your child or puppy who hasn’t quite gotten the hang of potty training yet, or your friend who had way too much to drink last night — there’s now a pee stain that you’re responsible for cleaning up. Your blankets and sheets will be fine if you throw them in the washer right away, but unlike your linens, mattresses can’t just be thrown into the washing machine.

How To Get Urine Smell Out Of A Mattress

Below you’ll find our step-by-step guide on how to completely clean urine out from your mattress, properly sanitize it, and remove any smells or stains left behind. The ingredients we recommend are normal household items that may already be a staple in your pantry, so no need to run to the store in the middle of the night.

Step 1: Remove Sheets & Bedding — Fast

As soon as you notice the urine stain, remove everything off of your mattress including sheets, blankets, or comforters, and throw them in the washing machine ASAP (double check that your comforter is machine washable). The sooner the better. If the urine is really set, though, we suggest you check out our simple guide on removing yellow stains from your bedding.

Step 2: Blot The Urine Area On Your Bed

Blot away all the extra liquid on the mattress with your towel or paper towel. Pro tip: don’t rub, dab! That way, you don’t push the stain deeper into the fibers of your mattress.

Step 3: Spray Down Your Mattress

Spray down the urine-stained area with a generous layer of vinegar. We recommend you use straight vinegar without any dilution if there is a strong urine odor, because it’s the best way to tackle the stubborn smell. Otherwise, you’ll be okay with using a diluted vinegar mixture that’s 50% vinegar and 50% water.

Use a spray bottle to prevent over saturating your mattress with liquid, because you risk damaging the bed’s foam and you want it to dry in a timely manner. Let the vinegar penetrate the fibers of your mattress, and leave it for 10-20 minutes to really ensure you remove that nasty urine smell. After you’ve let it set, soak up the vinegar with your paper towels or cloth (not the ones you originally used to clean up the extra pee, ew).

Step 4: Sprinkle Baking Soda Over The Area

This will help to soak up any lingering odors, and should get rid of the vinegar smell as well. We recommend leaving the baking soda for a full work day, like 8 hours or more. You can even leave it overnight if you want to be extra careful. Don’t worry about not being able to sleep on it though — you can just throw a pair of clean sheets over the mattress and get back to cleaning in the morning.

Step 5: Vacuum Up The Baking Soda

After eight hours or so (even longer if you can), vacuum up all the baking soda from your mattress. Use the attachment piece that should have come with your vacuum to make the process a bit easier, or even a handheld mini vacuum. Make sure to go over the surface multiple times — this isn’t a one-and-done type deal. If you rush through this step you may not get all the baking soda out of your mattress. And voila! The urine accident should be all but forgotten (until the next time).

How To Get Urine Out Of A Memory Foam Mattress?

Step 1: Remove sheets and bedding and set them aside to wash.

Step 2: Using gloves, blot the affected area on the mattress by using generous stacks of paper towels and firm pressure. Remove as much moisture as possible, swapping out the paper towels as soon as they become saturated. Don’t rub as this will make the stain worse.

Step 3: Fill a spray bottle with white vinegar and lightly coat the urine-stained area. Let sit for one hour and then blot dry with the same technique used in Step Two.

Step 4: Fill a spray bottle with a mixture of half water and half color-safe laundry detergent. Repeat the same process as in Step Three.

Step 5: Cover the treated area with a generous layer of baking soda and let it sit for up to a full day. Vacuum it up when dry.

Step 1: Blot as much moisture as you can out of the futon mattress, acting as quickly as possible.

Step 2: Fill a spray bottle with either white vinegar or rubbing alcohol to cover the affected area, then blot it dry. Repeat if necessary.

Step 3: Use a damp rag to remove any trace of the vinegar or rubbing alcohol.

Step 4: Cover the area with baking soda, letting it sit for several hours until dry. Use a vacuum to remove the baking soda once it has absorbed all of the moisture.

What You’ll Need To Clean Up Pet/Animal Urine:

  • Liquid detergent (a few drops)
  • Optional: essential oils, lemon water
  • Optional: rubber gloves, a blow dryer or standing fan

How To Get Dog And Cat Pee Out Of A Mattress

If one of your furry friends had something to do with the wet spot on your mattress, the odor can be a little smellier than that of human urine. That’s because pet urine is more concentrated, and contains significant amounts of alkaline and acidic substances. In this case, there are slightly different steps you should follow to make sure the pee, and its smell, are gone for good.

Step 1: Throw Your Linens In The Wash

Like human urine, you’ll want to wash your blankets and sheets right away to prevent the urine from staining or ruining your linens.

Step 2: Sprinkle baking soda, Vacuum, Repeat

Unlike cleaning humane urine from a mattress, you should first spread baking soda over the urine spot when dealing with pee from your pet. Why? The goal is to absorb all of the urine out of the bed first. You should notice the baking soda begin to darken in color, and when that happens, vacuum up the baking soda. From here, you’ll want to repeat this process until the baking soda stays white in color.

Step 3: Spray Down The Spot

Combine a mixture containing 8 oz of hydrogen peroxide, three tbs of more baking soda, and a few drops of liquid detergent in a spray bottle. You can also add a couple drops of your favorite essential oil or lemon water to leave a more pleasant smell on your mattress.

Spray down the spot with your mixture, and coat your mattress with a generous layer without completely soaking it. Also, you should make sure it’s all even.

Step 4: Vacuum The Residue

Vacuum up the excess residue after the sprayed-down spot has completely dried, and your mattress should look (and smell) like it’s back to normal.

You can also follow these same steps if you’re trying to clean up urine that has already dried from when you were out of town or asleep during the night. It’ll work on both dried animal urine, and dried human urine.

Future Prevention

If it was your child or your loved one who left the urine, there are steps you can take to prevent another big clean up in the future. You can purchase a protective covering that’s actually quiet, comfortable, and will keep your mattress fresh and clean. You can also get a sealed protector for things like pillows and duvets. As an added bonus, sealed coverings will protect you from dust mites and other unwelcome allergens.

You can also consider getting a waterproof mattress protector. Not only will they protect your mattress from your child’s or animal’s pee mishaps, they’ll extend the life of your mattress overall and protect your warranty. There are some popular protectors that won’t break the bank on Amazon.

If it was your animal that peed on your mattress, you’ll want to make sure it doesn’t happen again in the future. Dogs especially have a strong sense of smell, and may instinctively return to that spot to claim their territory (a.k.a. continue peeing).

Make sure the odor is completely gone, and bring in some extra reinforcements with commercial dog repellents, or a DIY remedy like cayenne pepper. Spray the repellent/ spread small bits of cayenne pepper to keep your dog from peeing on the spot again. Don’t worry, the cayenne pepper doesn’t hurt your pup/animal. It contains a certain molecule that slightly bothers their skin without hurting them. Kind of like an uncomfortable sweater your grandma knitted for you.

If the culprit was your too-drunk-to-function buddy, then the biggest advice we have for them is to take it easy, and slow down.

Important Things To Remember

Whether you’re cleaning urine left by your cat or from your 4-year-old who had an accident, there are a few key things you should keep in mind.

Act Fast

The longer urine sits (especially your animal’s urine which is much stronger than yours), the better chance it has to leave a nasty stain or lingering smell. That means, if you notice the urine right away, don’t put it off because you don’t feel like dealing with it. Get to cleaning right away.

If the stain happened while you were out of town and the stain sat a few days, you’ll just have to put in a bit of extra TLC and time when you’re cleaning your mattress.

Avoid Using Harsh Chemicals

Your run-of-the-mill store brand carpet cleaner is not a good alternative to clean urine out of a mattress. Many cleaning products contain chemicals that are harmful for humans and animals, and you don’t want that inside the mattress you sleep on every night. The strong odor from these harsh chemicals like bleach or disinfectants can also be a little too overpowering for your pet.

What is the danger of urine in a mattress?Leaving traces of urine in a mattress can cause many problems. For one, animals that have urinated on a mattress may repeat the behavior if the smell remains. Long-term exposure to the chemicals found in urine, especially pet urine, can also be harmful to health.

What’s the difference between cleaning fresh urine and dry urine from a mattress?Fresh urine is much easier to clean from a mattress than dry urine. In fact, you may find that attempting to remove urine stains once they have dried is nearly impossible most of the time.
