Most mattresses can be cleaned effectively with baking soda, an enzyme cleaner, and a vacuum — no soaking required, no harsh chemicals needed. The key is working in the right order: dry methods first, wet spot-cleaning second, then a full dry before you put bedding back on.

Step 1: Strip and Vacuum
Before anything touches that mattress surface, pull off every layer — sheets, mattress pad, protector, pillows. Toss them in the wash while you work. A bare mattress is a lot easier to clean, and washing your bedding at the same time means you’re not putting dusty linens back onto a freshly cleaned surface.
Once it’s bare, grab your vacuum with the upholstery attachment. Work in slow, overlapping rows from the top of the mattress to the bottom. Don’t rush this part — a standard queen mattress has roughly 40 square inches of surface piping and tufts where dead skin cells, dust mites, and debris pack in tight. Run the attachment along every seam, every button tuft, and both side panels.
Why does vacuuming come first? Wet cleaning over loose debris turns dust into mud and drives particles deeper into the fabric. A thorough dry vacuum pass removes the bulk before you introduce any moisture, which means your spot-cleaner or enzyme spray can actually reach the stain rather than sitting on top of a layer of grime. Consumer Reports recommends the upholstery attachment specifically — the beater-bar setting meant for carpet can damage mattress fabric over time.
Step 2: Spot-Clean Stains by Type
Different stains need different chemistry. Using the wrong approach can permanently set a stain or spread it wider. Always blot — never scrub. Scrubbing works the stain sideways into surrounding fibers and deeper into the foam layers underneath.
Urine stains: Use cold water only. Hot water above about 130°F denatures the proteins in urine and bonds them to fabric fibers — that’s what makes the stain permanent. Blot up as much moisture as you can with a dry towel first, then apply an enzyme-based cleaner directly to the stain. Let it sit for 10–15 minutes so the enzymes can break down the uric acid crystals that cause both the stain and the lingering odor. Blot dry. Repeat if needed.
Blood stains: Cold water is non-negotiable here. Blood contains hemoglobin, and even warm water can coagulate it into the fabric. Mix a small amount of 3% hydrogen peroxide (standard drugstore concentration) with cold water — roughly a 1:2 ratio — and dab onto the stain with a clean cloth. You’ll see it fizz slightly as it reacts with the proteins. Blot, don’t rub. For dried blood, you may need two or three applications.
Sweat and yellow stains: These are protein and oil buildup from years of body chemistry. Make a paste of baking soda and a small amount of dish soap with just enough water to create a thick consistency. Apply it directly to the yellowed area, let it sit for 30 minutes, then blot away with a damp cloth. The alkalinity of the baking soda helps lift the acidic residue.
General mystery stains: An enzyme cleaner handles most of them. Apply, let dwell for 10 minutes, blot clean. If a stain has been sitting for weeks or months, it may not fully lift — but enzyme cleaners will reduce discoloration and knock out any associated odor.
Step 3: Deodorize with Baking Soda
Baking soda is sodium bicarbonate, a mild alkali with a pH of around 8.3. Most biological odors — sweat, urine residue, pet smells — are acidic in nature, typically in the pH 4–6 range. When baking soda contacts those odor molecules, the acid-base reaction neutralizes them rather than just masking them with fragrance.
Sprinkle baking soda generously across the entire surface of the mattress. Don’t be stingy — you want a light but even layer over every inch, not just the spots you treated. Then leave it alone.
The longer it sits, the better it works. Good Housekeeping recommends a minimum of 8 hours; overnight is ideal. If you can time this so the mattress sits bare through the night — or better yet, on a sunny afternoon with the windows open — you’ll get the best results. Sunlight provides natural UV exposure that helps neutralize bacteria on the surface.
After the dwell time, vacuum the baking soda off completely using the upholstery attachment again. Go over the surface twice to pull up as much residue as possible. Any leftover powder will feel gritty against your sheet and may irritate skin.
Step 4: Air Dry Completely
This step is not optional and it’s not something you can rush. Putting even slightly damp bedding back onto a mattress — or flipping your mattress before it’s fully dry — traps moisture inside the foam layers. Memory foam and latex foam can’t release interior moisture the way coil mattresses can. Trapped moisture inside foam creates mold within days, and once mold is inside a mattress, there’s no safe way to remediate it. The mattress has to go.
For surface cleaning where you used minimal moisture, plan on 6–8 hours of drying time with good air circulation. Open windows, run a ceiling fan on high, or set a box fan near the mattress blowing across the surface.
If you used more liquid — say, a generous application of enzyme cleaner on a large urine stain — bump that to a full 24 hours before adding any bedding. A dehumidifier in the room speeds the process significantly if you have one. Don’t be tempted to use a hair dryer or space heater directly on the mattress; concentrated heat can break down foam and void some warranties.
How Often Should You Clean a Mattress?
Every 6 months at minimum. That’s the standard maintenance cycle recommended by Sleep Foundation: a full strip, vacuum, baking soda treatment, and spot-check for any emerging stains. Set a reminder for spring and fall — it lines up naturally with the seasonal deep-clean most people do anyway.
After any liquid spill, clean immediately. The longer urine, sweat, or any biological fluid sits, the deeper it penetrates and the harder it is to lift. A fresh spill that’s blotted within 5 minutes is dramatically easier to clean than one that’s been sitting overnight.
If you have allergies or asthma, quarterly cleaning is worth it. Dust mites peak in humid summer months — roughly 1 to 10 million mites can live in a single mattress, according to Sleep Foundation data. Vacuuming every 3 months, combined with a high-quality mattress protector, keeps allergen accumulation in check between deeper cleans.
Frequently Asked Questions
Can you steam clean a mattress?
It depends on the mattress type. Steam cleaning is effective for innerspring mattresses — the high temperature kills dust mites and bacteria. But it’s not recommended for memory foam or latex. Steam introduces significant moisture that foam can’t release quickly, and the heat can break down the cellular structure of foam layers over time. If you have a foam mattress, stick to dry methods and minimal-moisture spot cleaning.
What removes yellow stains from a mattress?
Yellow stains are almost always sweat or body oil accumulation — years of sleeping, not a single spill. A baking soda paste (baking soda + a drop of dish soap + just enough cold water to form a thick paste) applied for 30 minutes and then blotted away works well on moderate yellowing. For deeply set discoloration, a dedicated enzyme cleaner formulated for protein stains will do more heavy lifting. Don’t expect to fully whiten an old mattress — significant yellowing after years of use is normal, and a mattress protector going forward is the real fix.
How do you get urine out of a mattress without a vacuum?
Start by blotting as much liquid as you can with a stack of dry towels — press firmly and swap towels as they saturate. Then apply an enzyme cleaner, let it sit for 15 minutes, and blot again thoroughly with clean towels. Sprinkle baking soda generously over the area and let it sit for several hours to absorb residual moisture and neutralize odor. Then brush or wipe off the baking soda with a dry cloth. It’s messier than vacuuming, but it works. A handheld vacuum or a shop vac makes the final step much cleaner if one’s available.
Can I use bleach on a mattress?
No. Bleach damages fabric fibers and can degrade the foam underneath, and it’s genuinely hazardous in an enclosed bedroom — residual chlorine off-gassing from a mattress you sleep on for 7–8 hours a night isn’t something you want to breathe. It also won’t effectively remove biological stains because it bleaches color rather than breaking down protein. Enzyme cleaners do that job without the health risk or material damage.
How do I clean a memory foam mattress differently?
Memory foam can’t handle submersion or heavy moisture. Don’t use a steam cleaner, don’t drench stains, and never put a memory foam mattress in the washing machine (yes, people try). Spot-clean with the minimum amount of liquid necessary — apply enzyme cleaner to a cloth first, then dab that onto the stain rather than spraying directly onto the foam. Baking soda deodorizing works the same way on foam as on other types. The main difference is drying time: foam needs longer, often 24 hours or more, because it can’t breathe the way coil-supported mattresses do.
Does baking soda actually work on mattress odors?
Yes, and the chemistry is straightforward. Baking soda’s alkaline pH neutralizes the acidic compounds responsible for most biological odors. It doesn’t just absorb smells the way activated charcoal does — it chemically reacts with them. The catch is contact time. A 30-minute application does very little. You need at least 8 hours, ideally overnight, for meaningful odor reduction. If odors are severe — old pet accidents or years of accumulated sweat — you may need to do the baking soda treatment twice, or follow up with an enzyme cleaner before the baking soda pass. If you’re weighing options here, our guide to how to clean a mattress stain covers the trade-offs in more detail.
