How to Clean Mattress Stains — Toronto Home Guide

Mattresses can't be submerged or soaked — excess moisture trapped inside creates mould that is impossible to remove. All mattress cleaning uses minimal liquid and relies on blotting, not rubbing.

General Approach

• Always blot — never rub or scrub, which spreads stains and pushes liquid deeper
• Use as little liquid as possible — apply cleaners with a spray bottle or dampened cloth rather than pouring
• Dry thoroughly after every treatment — a fan pointed at the mattress dramatically speeds drying

Urine Stains

1. Blot fresh urine immediately with a dry cloth — absorb as much as possible before treating
2. Spray an enzyme cleaner (Nature's Miracle or similar) over the affected area — enzyme cleaners break down the proteins and uric acid that cause the smell
3. Let sit for 10–15 minutes
4. Blot with a clean dry cloth
5. Sprinkle baking soda over the damp area and let sit for several hours or overnight to absorb residual moisture and odour
6. Vacuum off the baking soda

Blood Stains

1. Use cold water only — hot water sets blood stains permanently
2. Mix 1 part hydrogen peroxide (3%) with 1 part cold water
3. Apply sparingly to the stain with a cloth
4. Blot — the peroxide will fizz as it breaks down the blood
5. Blot with a clean damp cloth to rinse, then dry with a fan

Sweat and Yellow Staining

1. Mix equal parts hydrogen peroxide, dish soap, and baking soda into a paste
2. Apply to the stained area with a cloth
3. Let sit 30 minutes
4. Blot off and allow to dry completely

Tips

• A mattress protector is the best investment for mattress longevity — a waterproof cover prevents most stains from reaching the mattress at all
• Vacuum the mattress every few months to remove dust mites, skin cells, and dust from the surface
• Rotate the mattress head-to-foot every 3–6 months to even out wear
