One morning, I woke up realizing my bed wasn’t just warm and cozy. There it was, that unmistakable damp spot. Yep, it happened to me too. And the worst part? It was on my memory foam mattress.
If you’ve ever faced this, you know the mix of panic and disbelief that follows. Whether it’s your kid, your pet, or even an unfortunate accident during sleep, don’t worry. I’ve been there, and trust me, you can fix it. In this guide, I’ll show you how to get pee out of a memory foam mattress quickly, safely, and without any lingering odors.
Step-by-Step Guide — How to Get Pee Out of a Memory Foam Mattress Fast

Cleaning pee might sound unpleasant, but once you know the method, it’s actually super easy. Follow these simple steps.
Step 1: Act Fast Blot, Don’t Rub
Grab some paper towels or a clean cloth and start blotting the wet area. Don’t rub. Rubbing pushes the pee deeper into the foam, which makes things worse.
I made that mistake the first time and ended up doubling my work. So learn from me, press, lift, repeat. Keep blotting until no more moisture transfers to the towel.
Step 2: Make a Cleaning Solution at Home
Now it’s time to mix up your magic cleaner. In a spray bottle, combine:
- 1 part white vinegar
- 1 part water
- A few drops of mild dish soap (optional)
Spray enough to dampen the affected area, but don’t drench it. Vinegar is the real hero here; it neutralizes odors naturally and breaks down uric acid (the smelly culprit).
Step 3: Let It Sit and Do the Work
Let the vinegar solution rest for about 10–15 minutes. This gives it time to work deep into the foam.
Think of it like this: you’re giving the vinegar a chance to fight the bacteria. And honestly, this is your “make a cup of tea and relax†moment. Cleaning pee doesn’t have to be stressful.
Step 4: Sprinkle Baking Soda Generously
Next, grab your baking soda, the ultimate odor absorber. Sprinkle it generously over the damp area. Don’t be shy!
The baking soda will pull out moisture and trap any leftover smells. For the best results, leave it overnight. If you can, open a window or use a fan nearby to speed up the drying process.
Step 5: Vacuum and Freshen Up
The next morning, vacuum the entire area thoroughly. You’ll see the baking soda disappear and with it, the odor.
Honestly, this step always surprises me. You’ll wake up to a mattress that smells fresh and looks clean, no stains, no odor, just comfort. This method works great for both new and old pee stains on a memory foam mattress.
How to Remove Dried Pee Stains from Memory Foam

Old pee stains can be a bit more stubborn. If you notice a yellowish patch or a faint odor, here’s what to do.
Mix up this stronger solution:
- 1 cup hydrogen peroxide
- 2 tablespoons baking soda
- A few drops of dish soap
Spray it lightly over the stained area, you’ll see it fizz (that’s a good sign!). Let it sit for about 10–15 minutes, then gently blot with a clean towel. Once dry, vacuum up any residue.
Pro tip: Always test this solution on a small hidden spot first to ensure it doesn’t discolor your fabric.
Getting Rid of Odor Completely (Even Pet Smells!)
Now let’s talk about that stubborn smell, especially if you have pets. Pet urine often smells stronger because of ammonia. The fix? Use an enzymatic cleaner, which breaks down organic compounds instead of just masking them.
You can find these at most pet or grocery stores. They’re completely safe for memory foam. For an extra touch, add a few drops of lavender or eucalyptus oil after cleaning to give your mattress a calm, clean scent.
That’s another effective tip for how to get pee out of a memory foam mattress and make it smell amazing!
Prevent Future Accidents — Make Your Life Easier
After my first cleanup mission, I made a promise to myself: never again without protection!
Here’s what I recommend:
- Use a waterproof mattress protector – It keeps all liquid away from your foam layer.
- Get a washable cover – Perfect for quick cleaning.
- If you have kids or pets, go for pet-friendly bedding that’s easy to remove and wash.
Trust me, once you’ve spent an evening cleaning pee, you’ll never skip a mattress protector again!

FAQ’s
No, bleach can damage the foam and create a strong chemical smell. Stick with vinegar, baking soda, or enzyme cleaners.
Usually 8–10 hours. For faster drying, place a fan near the mattress or let it sit under gentle sunlight.
Repeat the vinegar-baking soda process or use an enzymatic cleaner once more. Persistent smells are usually from deep-seated urine crystals. The second round always helps.
