Urine is drawn out of a mattress best by blotting with dry towels and using a wet-dry vacuum or upholstery extractor. These methods remove liquid from inside the mattress instead of only treating the surface.
Baking soda can absorb leftover moisture and odor near the top, but it will not pull a large amount of urine from deep foam. The sooner you act, the more you can remove.
What Works Best for Fresh Urine
Dry towels
Start with clean, absorbent towels.
Press the towels firmly into the wet area. Use your hands, knees, or a heavy flat object to apply pressure. Do not rub. Rubbing can spread the urine across a larger part of the mattress.
Replace the towel when it becomes damp. Keep pressing with fresh towels until they stop picking up much moisture.
White towels are useful because you can see how much liquid is still coming out.
A wet-dry vacuum
A wet-dry vacuum can remove liquid that towels cannot reach. Use an upholstery attachment if one is available.
Move the nozzle slowly over the wet area. Make several passes from different directions. Do not use a regular household vacuum on a wet mattress unless its instructions clearly say it can pick up liquids.
A wet-dry vacuum is often the most practical choice for:
- Thick mattresses
- Foam mattresses
- Large accidents
- Guest beds
- Kids' beds
- Mattresses that cannot be moved easily
Empty and clean the vacuum according to its instructions after use.
An upholstery extractor
An upholstery extractor sprays a small amount of cleaning solution and pulls it back out. It can help remove urine from below the fabric surface.
Use as little liquid as possible. Mattresses are thick and can stay damp for a long time. Too much cleaning solution may push moisture deeper into the mattress.
Check the mattress manufacturer's cleaning guidance before using an extractor. Some foam and layered mattresses should only be spot-cleaned.
What Baking Soda Can and Cannot Do
Baking soda can absorb some moisture left near the surface. It can also help reduce lingering odor after most of the urine has already been removed.
It is not a substitute for blotting or extraction.
To use it:
- Blot or extract as much liquid as possible.
- Sprinkle a generous, even layer of baking soda over the damp area.
- Leave it in place until the mattress feels dry. This may take several hours.
- Vacuum it up with a dry vacuum only after the powder is fully dry.
Do not soak the baking soda with water. Wet baking soda can form a paste that is hard to remove from mattress fabric.
Does Salt Draw Urine Out of a Mattress?
Salt absorbs moisture, but it is usually not the best choice for a mattress.
It can become gritty, leave residue, and be difficult to vacuum from textured fabric. Large amounts may also work into seams and quilting.
Dry towels, a wet-dry vacuum, and baking soda are easier to control and remove.
Will Cornstarch Pull Urine Out?
Cornstarch can absorb a small amount of surface moisture, but it may clump when wet. Those clumps can stick to fabric and mattress seams.
Baking soda is usually easier to spread, dry, and vacuum. Neither powder will remove as much liquid as firm blotting or suction.
How to Remove Fresh Pee From a Mattress
1. Strip the bed
Remove sheets, blankets, protectors, and mattress pads right away.
Check each item's care label before washing, drying, bleaching, or using hot water. Washable layers may need to be rinsed or treated before a normal wash cycle.
2. Blot the wet area
Press dry towels into the stain. Work from the outside toward the center so the wet area does not spread.
Keep changing towels until they come away mostly dry.
3. Extract deeper moisture
Use a wet-dry vacuum or upholstery extractor if the mattress still feels wet below the surface.
Do not flood the mattress. Use short passes and remove more liquid than you add.
4. Treat the remaining residue
A mattress-safe enzyme cleaner can help break down urine residue that causes odor. Enzyme cleaners contain ingredients that break down organic material.
Follow the product label closely. Test it on a hidden area first, and check the mattress maker's cleaning instructions.
Do not mix enzyme cleaner with bleach, ammonia, vinegar, peroxide, or other cleaners. Mixing products can damage fabric or create unsafe fumes.
5. Blot again
After the cleaner has had the label-recommended contact time, blot the area with fresh towels. Use a wet-dry vacuum if the instructions allow it.
6. Apply baking soda
Cover the damp area with baking soda. Let it sit until the mattress is completely dry, then vacuum it up.
7. Dry the mattress fully
Stand the mattress on its side when possible so air can reach more of it. Open windows, run a fan, or use a dehumidifier.
Urine is drawn out of a mattress best by blotting with dry towels and using a wet-dry vacuum or upholstery extractor; the protector keeps liquid from reaching the mattress, while the pad catches smaller accidents and is easier to wash quickly.
Do not make the bed while the mattress is still damp. Trapped moisture can cause stale smells and damage mattress materials.
What About Old, Dried Urine?
Once urine has dried, there may be very little liquid left to draw out. The main problem is usually residue and odor.
Lightly apply a mattress-safe enzyme cleaner according to the label. Give it enough time to work, then blot or extract the treated area.
You may need more than one treatment for an old stain, but avoid soaking the mattress during repeated cleaning.
Baking soda can help with leftover surface odor after the mattress has been treated, but it does not break down dried urine by itself.
Should You Use Vinegar?
A diluted vinegar solution is often used for household odor cleaning, but it does not physically pull urine from a mattress. Towels and suction do that job.
Vinegar may also leave its own smell and may not be suitable for every mattress cover or foam layer. Check the mattress care instructions before using it.
Never combine vinegar with bleach or other cleaning chemicals.
Should You Use Hydrogen Peroxide?
Hydrogen peroxide may lighten some stains, but it can also fade or discolor mattress fabric. It does not replace blotting or extraction.
Some homemade mixtures combine peroxide with other ingredients, but these can be difficult to control on foam and quilted mattress surfaces. A cleaner labeled for mattresses or upholstery is usually a simpler beginner-friendly choice.
Test any product in a hidden area and follow the current product label.
What Not to Do
Avoid these common mistakes:
- Do not scrub the wet area.
- Do not pour large amounts of water onto the mattress.
- Do not use a steam cleaner unless the mattress maker allows it.
- Do not use high heat to force the mattress dry.
- Do not mix cleaning products.
- Do not place sheets over a damp mattress.
- Do not use a regular dry vacuum to collect liquid.
- Do not assume baking soda has removed moisture from deep foam.
Too much liquid is one of the biggest problems. A mattress can feel dry on top while still holding moisture inside.
How Long Does a Mattress Take to Dry?
Drying time depends on how much liquid entered the mattress, the mattress material, room airflow, and humidity.
A small surface accident may dry within the same day. A thick foam mattress or heavily soaked area can take much longer.
Check the area with firm hand pressure. If it feels cool, damp, or softer than the surrounding mattress, it may still contain moisture.
Use fans and airflow rather than high heat. Keep pets and children away from the mattress until cleaners have dried and the room has been aired out.
When the Urine Has Reached Deep Foam
Deep urine is harder to remove because many mattresses have several layers. Towels may only reach the top fabric, while liquid can move into foam underneath.
A wet-dry vacuum gives you the best chance of removing deeper moisture at home. Even so, a heavily soaked mattress may keep some odor or staining.
Check whether the mattress cover is removable before taking it off. Some covers should not be removed, even when they have a zipper. Removing the wrong cover can damage the mattress or affect how it is meant to be used.
For a large or repeated accident, check the manufacturer's cleaning guidance or contact a professional upholstery or mattress cleaner.
How to Protect the Mattress Next Time
A washable waterproof mattress protector can keep most accidents from reaching the mattress.
Choose one that fits the mattress depth. Pocket depth is the height of mattress the protector is designed to cover. Measure from the bottom edge to the top surface, including any topper.
For kids' beds, guest rooms, shared beds, or pet-friendly homes, consider keeping a spare protector ready for laundry day. Two thin washable protectors can be easier to manage than one bulky mattress pad.
Check the current product listing and care label for waterproofing, fit, washing, and drying instructions.
Frequently Asked Questions
What draws the most urine out of a mattress?
Firm blotting with dry towels removes fresh surface urine. A wet-dry vacuum or upholstery extractor removes more liquid from below the surface.
Does baking soda pull pee out of a mattress?
Baking soda absorbs some leftover surface moisture, but it does not pull a large amount of urine from deep mattress foam. Remove as much liquid as possible before applying it.
How long should baking soda stay on a mattress?
Leave it until the mattress and powder are fully dry. This may take several hours. Vacuum the baking soda only after it is dry.
Can I use a regular vacuum on wet urine?
No. Use a wet-dry vacuum that is designed to collect liquid. A regular dry vacuum may be damaged and can create an electrical hazard when used on wet material.
What removes dried urine smell from a mattress?
A mattress-safe enzyme cleaner can help break down dried urine residue. Follow the product label, avoid soaking the mattress, and dry it fully afterward.
Should I pour water on the stain to rinse it?
Avoid pouring water onto the mattress. It may spread the urine and push moisture deeper into the foam. Use small amounts of cleaner and remove moisture with towels or suction.
Can a badly soaked mattress be saved?
Sometimes, but results depend on how deeply the urine entered and how quickly it was removed. A heavily soaked mattress may keep odor or moisture inside. Check the manufacturer's cleaning guidance or consider professional cleaning.
