Mattress Stain Removal Guide — Tested Methods
How to remove stains from a mattress, including blood, urine, sweat, and yellow discoloration. Safe methods that will not damage your mattress.

Mattress stains are uniquely challenging because you cannot just throw a mattress in the washing machine. You need to clean in place, use minimal moisture (to prevent mold growth inside the mattress), and let it dry completely. The most common mattress stains are blood, urine, sweat yellowing, and general body oils. We have found that a spray bottle of hydrogen peroxide (3%) is the single most useful tool for mattress stain removal — it works on blood, urine, and yellowing without over-wetting the mattress.
Never soak a mattress — excess moisture can lead to mold growth inside the mattress where you cannot see it. Use spray bottles to apply cleaning solutions lightly. After treatment, use a fan or open windows to ensure the mattress dries completely within a few hours. Consider using a waterproof mattress protector to prevent future stains.

Common Stains on Mattress
The best removal method depends on the type of stain, not just the surface. Use our Stain Finder to get a method tailored to your exact stain and surface combination, or browse the stain-specific guides below for detailed instructions.
Always test any cleaning solution on a hidden area of your mattress before applying it to the stain. Different materials within the same surface category can react very differently to cleaning agents. When in doubt, start with the mildest solution (cold water and dish soap) and escalate only if needed. Use our Product Finder to identify the right cleaner for your specific scenario.
