How to remove urine from your memory foam mattress (1)

Step 1: Assess the damage

First things first: assess the situation. Are you dealing with fresh urine, or does the stain look like it's been there for a while? Is it a lot of urine, or just a little? Is there a mild odor or do you need to deal with a more pungent odor? Understanding what you are working with will help you approach your cleaning method.

Another consideration is themattress typeWhat do you have. Foam mattresses tend to absorb liquids faster than other types, so working quickly to wick away moisture is key. Follow the same steps for a pillow top and Euro top.

If you got the stain shortly after it happened, that's good news. The fresher the stain, the easier it will be to clean. But it's important to act fast, before the urine has a chance to leak out. If you notice a dried urine stain on your mattress, don't worry. You may need a stronger solution, but cleaning dried urine from your mattress is still an option.

Step 2: Remove your bedding

Then remove the bedding and throw it in the washing machine - stat. (See our article onhow to wash sheetsfor more tips on how to keep them clean).

Stage 3: Blot to area

Gently press rags or paper towels over the area to remove excess moisture. Be careful not to rub it, as this can cause urine to seep further into the mattress. At this point, you'll want to open all the windows in the room and run a fan (if you can) to help increase airflow throughout the room.

Step 4: Clean

Vinegar is a powerful natural cleanser that helps break down uric acid found in urine, making it easier to eliminate. This method is best for cleaning a fresh urine stain on your mattress.

To create your solution, simply fill a spray bottle half with white vinegar and half with water. Saturate the area with the solution and apply a layer of baking soda to completely cover the stain. Let it sit for several hours or a whole day if you can! You should see the baking soda build up as it absorbs into the vinegar at this point. Finally, vacuum up the baking soda.

If the smell or stain won't go away, it may be time to break out the big guns. Hydrogen peroxide is perfect for tough stains because it's an oxidizer that kills bacteria and helps neutralize odors.

Note: Hydrogen peroxide can bleach some fabrics, so be sure to remove all bedding from the area before starting work!

For this solution, combine 8-10 ounces of hydrogen peroxide (3%) with 3 tablespoons of baking soda and 2-3 drops of dish soap. Shake to combine (do not shake). Spray to cover the stains well and leave to act for approximately one hour. Finally, use a damp cloth to gently rinse the area, then blot with the dry cloth to completely remove the solution.

An enzymatic cleaner like OxiClean can also do wonders for urine odor. These cleaners include ingredients that actually attack the source of the odor. Look for cleaners with protease enzymes specifically. To use, saturate affected areas of your mattress and allow to dry completely. You can also try covering the area with plastic wrap while the cleaner is running, which will help prevent evaporation.

How to get dog or cat urine out of the mattress

Do you have dog or cat urine on your mattress? Pet urine (especially cat urine) is known to smell a bit stronger than human urine; this is due to the amount of urea it contains, the main element in urine that breaks down into ammonia.

The instructions for cleaning up cat and dog urine are pretty similar, but it may take a bit of extra effort due to the smell. Here are the steps:

  1. Remove all bedding and blot the area with a clean cloth to remove as much of the liquid as possible. We recommend using disposable paper towels or old ready-to-throw-away bath towels.
  2. Create a solution of 50% white vinegar and 50% water in a spray bottle and lightly mist the area. The vinegar will help dissolve the stain and neutralize the odor.
  3. Let the area air dry.

Once dry, the stain and odor should be gone. If not, repeat the steps until there is no longer a lingering odor or visual indication of urine on your mattress. This is important as pets often return to places where they have urinated before! If you're having trouble removing the stain, you may need to turn to store-bought enzymatic cleaners or a hydrogen peroxide solution.

Advice:To double your efforts, sprinkle some baking soda on the stain after it's soaked in the vinegar solution and allow it to dry before vacuuming.

Is it bad to sleep on a urine-soaked mattress?

So let's say you, or your child or dog, have an accident. If it's in the middle of the night, you might be tempted to wait until morning to fix the problem or spend the night on the couch or guest bed. But that can be a big mistake.

Unfortunately, leaving urine on the mattress will only make it more difficult to clean later. In addition to starting to stink thanks to the ammonia in your urine, a wet mattress is the perfect breeding ground for nasty bacteria and mold. Gross!
