How to Clean a Mattress Properly: Step-by-Step Guide
Most people have never deep-cleaned a mattress. You wash your sheets, you flip the mattress occasionally, and you assume the rest takes care of itself. It does not. The average mattress absorbs several liters of sweat per year, along with dead skin cells, body oils, and whatever else ends up in bed with you. Here is how to clean it properly.

What You Need Before You Start
You need baking soda, a vacuum with an upholstery attachment, cold water, mild dish soap, a clean cloth or sponge, and an enzyme cleaner for any biological stains. Avoid bleach and hydrogen peroxide on most mattress types as both can break down foam and damage mattress covers. Do not soak the mattress. Water that penetrates deep into a mattress takes days to dry and creates ideal conditions for mold growth.
Step 1: Strip the Bed and Vacuum
Remove all bedding and wash it separately. Vacuum the entire mattress surface using an upholstery attachment. Pay attention to seams and edges where dust mites, skin cells, and debris accumulate. Vacuum the sides of the mattress as well. This step alone removes a significant amount of what makes a mattress unhygienic.
Step 2: Treat Stains
For fresh stains, blot immediately with a clean cloth and cold water. Never rub, which spreads the stain. For dried organic stains (the ones that come with spending a lot of time in bed), an enzyme cleaner is the most effective solution. Enzyme cleaners break down biological material at a molecular level rather than just masking it. Apply lightly to the stain, let it work for 10 to 15 minutes, then blot clean. Do not over-wet the area.
If this all sounds like more effort than it is worth, a waterproof layer between you and the mattress prevents most of this in the first place. See it on Amazon.
Step 3: Deodorize with Baking Soda
Sprinkle a generous layer of baking soda across the entire mattress surface. Work it gently into the fabric with a soft brush. Let it sit for at least 2 hours. Longer is better. Baking soda neutralizes odors by reacting with acidic and basic odor compounds rather than just covering them with fragrance. After the wait, vacuum the baking soda off thoroughly.
Step 4: Air and Dry
If possible, let the mattress air out near an open window or in a well-ventilated room for at least a few hours before remaking the bed. UV light from direct sun exposure kills bacteria and helps with odors, but keep this brief since extended UV exposure degrades foam.
The Easier Long-Term Solution
A waterproof blanket placed on the mattress surface before you add your regular sheets creates a barrier between you and the mattress that prevents most of what causes mattress contamination in the first place. The blanket goes in the washing machine. The mattress stays clean. The Pound Pad is specifically designed for this with a soft top surface that does not feel or sound like a plasticky protector.

Frequently Asked Questions
How often should you deep clean a mattress?
Deep cleaning every 6 months is a reasonable minimum. More frequent cleaning makes sense if you sweat heavily, have pets on the bed, or have had any spills or accidents.
Can you use baking soda to clean a mattress?
Yes. Baking soda is one of the most effective mattress deodorizers available. Sprinkle generously, let sit for 2 to 4 hours minimum, then vacuum thoroughly. It neutralizes odors rather than masking them.
What is the best cleaner for mattress stains?
An enzyme cleaner is most effective for organic stains because it breaks down biological material at a molecular level. Apply lightly to avoid over-wetting, let work for 10 to 15 minutes, and blot clean.
Can I use bleach on a mattress?
No. Bleach can break down foam layers and damage the mattress cover material. Use mild soap, cold water, and enzyme cleaners instead.
How do you stop a mattress from getting stained?
A waterproof mattress protector or waterproof blanket is the most effective prevention. A quality waterproof blanket creates a barrier that washes in the machine, keeping the mattress itself clean indefinitely.
