Why It’s Important to Clean Your Mattress
Your mattress is where you spend nearly a third of your life. Over time, it accumulates sweat, body oils, dead skin cells, allergens, dust mites, and occasional spills. If left untreated, these can lead to odors, discoloration, and even respiratory issues. Learning how to clean a soiled mattress helps you protect your health, extend mattress life, and ensure better sleep quality.
According to sleep experts, a clean mattress can significantly improve indoor air quality and reduce allergic reactions. For a full breakdown of mattress hygiene, read our detailed guide.

How to Clean Common Mattress Stains
Whether you’re dealing with spills, pet accidents, or just general grime, these step-by-step tips will show you how to clean a soiled mattress safely and effectively.
Urine Stains
Urine is one of the most common reasons people search how to clean a soiled mattress. Act fast. First, blot up as much liquid as possible with a clean cloth. Then spray the area with a mix of hydrogen peroxide, a few drops of dish soap, and baking soda. Let it sit for at least 8 hours, then vacuum thoroughly.
Pro Tip: Always patch test your solution on a small, hidden area to avoid discoloration.
Removing Odors
Odors are often caused by lingering bacteria or mildew. To eliminate them, mix one part white vinegar with one part water and lightly mist the affected area. Allow it to air dry fully. Once dry, sprinkle baking soda liberally and let sit for several hours or overnight before vacuuming.
This method is gentle, safe, and especially useful after cleaning bodily fluids or food stains.
Deep Cleaning with Steam
If surface cleaning isn’t cutting it, a handheld steam cleaner can help sanitize your mattress. Use short, controlled bursts of steam and avoid soaking the mattress. Always follow with plenty of drying time—ideally in a well-ventilated room or with a fan nearby.

Dealing with Fresh Spills
For fresh accidents, time is of the essence. Blot—not rub—the area with a clean towel. Then cover it in baking soda to draw out moisture and odor. Let it sit for a few hours before vacuuming clean.
Preventing Future Mattress Stains
Once you’ve gone through the effort of cleaning, the last thing you want is a repeat offense. That’s where prevention comes in. A waterproof mattress protector acts as a barrier between spills and your mattress core. It’s washable, breathable, and prolongs the life of your bed.
