We’ve all dealt with urine stains on mattresses, whether from pets, kids, or accidents. Don’t worry – even though it seems scary at first, you can clean it up with the right steps. Let’s learn how to fix this common problem, whether the stain is fresh or has been there for a while.
According to Martha Lew, a cleaning expert at the American Cleaning Institute, “The key to removing urine from a mattress is to act quickly and use cleaning products that break down both the stain and the odor-causing bacteria.”
The good news is you don’t need fancy cleaners to fix this mess. Most of the things you’ll need are probably already in your home, like dish soap, white vinegar, and baking soda. The trick is knowing how to use them the right way to get rid of both the stain and the smell. Whether you’re dealing with your child’s bedwetting accident or your pet’s mistake, these simple steps can help save your mattress from lasting damage.
Fresh Urine Requires Immediate Action

When you discover fresh urine on your mattress, taking immediate action is essential to prevent permanent damage.
We’ll need to start by removing bedding and blotting the area with clean towels to absorb excess liquid.
Next, we’ll create a cleaning solution using white vinegar, water, and laundry detergent to neutralize odors.
Finally, we’ll apply baking soda to tackle remaining mattress stains.
Let’s look at what we need to know about cleaning urine from a mattress, including both helpful tips and common mistakes to avoid.
We’ll break down the process into clear steps that anyone can follow, from the initial blotting to the final vacuum cleanup.
Whether you’re dealing with a fresh accident or an old stain, we’ll guide you through the most effective cleaning methods that protect your mattress while eliminating both stains and odors. Quick action is essential for effective odor removal since urine can spread rapidly through mattress layers.
Things to Do When Cleaning Urine From a Mattress
When cleaning urine from a mattress, it’s crucial to act quickly and follow a systematic approach to guarantee the best possible results. The process requires careful attention to detail and the right combination of cleaning solutions to effectively remove both the stain and odor, while preventing any damage to the mattress material.
- Immediate blotting – Use clean, white towels to absorb as much urine as possible without rubbing the stain.
- Vinegar solution application – Mix equal parts water and white vinegar, spray on the affected area and let sit for 10-15 minutes.
- Moisture absorption – Apply a generous layer of baking soda over the treated area and allow it to sit for 8-10 hours.
- Deep cleaning treatment – For stubborn stains, use a mixture of hydrogen peroxide, baking soda, and dish soap.
- Thorough drying – Confirm the mattress is completely dry before making the bed.
- Regular inspection – Check mattress periodically for any signs of residual stains or odors.
- Preventive measures – Consider using a mattress protector to prevent future accidents.
Things to Avoid When Cleaning Urine From a Mattress
When cleaning urine from a mattress, it’s essential to avoid common mistakes that can worsen the situation or cause permanent damage to your mattress.
Using the wrong cleaning methods or products can lead to lingering odors, stains that set deeper into the fabric, and potential deterioration of the mattress materials, ultimately compromising both its cleanliness and longevity.
- Bleach and harsh chemicals – These can break down mattress materials and create toxic fumes while failing to eliminate urine odors.
- Aggressive scrubbing – Rough cleaning motions force the urine deeper into mattress layers, making the stain and odor harder to remove.
- Excessive water – Too much moisture can soak into the mattress foam, creating an environment for mold and mildew growth.
- Steam cleaning – High heat can permanently set urine stains and proteins into the mattress fibers.
- Fabric softeners – These products mask rather than eliminate odors and can leave residue that attracts dirt.
- Direct heat – Using hairdryers or heaters can set stains and damage mattress materials.
- Colored cleaning cloths – Dyes from colored towels or rags can transfer onto the mattress when wet.
- Waiting too long to clean – Allowing urine to sit and dry makes it considerably more difficult to remove completely.
