What You'll Need Before You Start
Learning how to deep clean orthopedic memory foam beds starts with the right supplies, because memory foam is a porous material that traps liquid and holds it. At Mafé Pets, we build our beds around high-density orthopedic memory foam with a sealed waterproof liner, so we know exactly what these mattresses can survive. Gather these items first:
- Vacuum with an upholstery tool and a soft brush attachment
- Baking soda for moisture absorption and odor control
- Distilled water, which avoids mineral stains
- White vinegar for mild disinfection
- A mild detergent or a pet-safe enzymatic cleaner
- Clean white cloths and a spray bottle
- A mattress protector for everyday defense
Step-by-Step Deep Cleaning for Memory Foam Beds
Deep cleaning a memory foam bed takes about an hour of hands-on work, plus 12 to 24 hours of drying time depending on your indoor humidity. Work in this order: vacuum, spot treat, deodorize, then air dry. Never soak the foam core, memory foam is an open-cell material, meaning liquid wicks inward through interconnected pores rather than sitting on the surface, and once water reaches the core it can take days to escape.
Vacuuming and Debris Removal
Start with debris removal before any liquid touches the bed. Vacuum both sides of the mattress with an upholstery tool on low suction. A soft brush attachment lifts hair and dander without tearing the surface.
Spot Cleaning vs. Deep Cleaning
Spot cleaning handles fresh spills in minutes. Deep cleaning refreshes the whole mattress every few months. Most owners only need spot cleaning week to week.
Drying and Mildew Prevention
This is the step most guides gloss over, and it's the one that determines whether your bed survives the cleaning. Memory foam holds moisture in its cell structure long after the surface feels dry. A surface that reads dry to the touch can still be damp 1 to 2 inches down.
Target conditions for drying:
- Humidity: Keep the room below 50% relative humidity. Above 60%, foam can stay damp for 48 hours or more, which is the window where mildew takes hold.
- Airflow: Point a box fan or floor fan directly across both faces of the mattress. Moving air pulls moisture off the surface faster than still air by a wide margin.
- Temperature: Room temperature (roughly 68-75°F) is ideal. Cold rooms slow evaporation; hot, direct sun degrades the foam.
- Position: Stand the mattress on its edge if the foam is firm enough to hold shape, or lay it flat and flip it every few hours so both faces get airflow.
- Dehumidifier: In basements, bathrooms, or humid climates, run a dehumidifier in the same room. This is the single biggest lever if you live somewhere muggy.
How to Remove Urine from Memory Foam
Removing urine from memory foam is a race against gravity. Urine is a biological fluid, and it sinks fast into porous foam, so act within minutes.
- Blot up as much liquid as possible with a clean towel. Stand on it if you need pressure.
- Mix one part white vinegar with three parts distilled water in a spray bottle.
- Spray the stain lightly. Do not saturate the foam.
- Blot again, then sprinkle baking soda over the area to pull out remaining moisture and odor.
- Let it sit for several hours, then vacuum the powder away.
- Air dry completely before the cover goes back on.
Best Enzymatic Cleaners for Pet Beds
The best enzymatic cleaners for pet beds are the ones formulated for urine and other biological fluids, not general-purpose sprays. Look for a cleaner that lists enzymes on the label and states it's safe for pets once dry.
What to check before you buy:
- Enzyme content: Protease and amylase break down urine proteins.
- Pet safety: The label should say it's safe for pets after drying.
- Scent: Fragrance-free options suit sensitive dogs.
- Foam compatibility: Avoid cleaners with bleach or ammonia, which damage foam and attract repeat marking.
How Often to Wash Dog Bed Covers
Wash dog bed covers every two weeks, and weekly if your dog sheds heavily, drools, or has allergies. The cover takes the daily abuse, so it needs more frequent washing than the mattress inside.

A simple schedule:
| Task | Frequency | Time Needed |
|---|---|---|
| Vacuum the mattress | Weekly | 5 minutes |
| Wash the cover | Every 2 weeks | 1 hour |
| Spot clean accidents | Immediately | 10 minutes |
| Deep clean the mattress | Every 3-4 months | 1 hour plus drying |
Cleaning Different Foam Densities and Eco-Friendly Options
Not all orthopedic memory foam is the same, and the differences change how you clean it. The three variables that matter most are density, infusion type, and cell structure.
Density: The Biggest Variable
Density is measured in pounds per cubic foot (lb/ft³). Most orthopedic pet beds fall between 2.5 and 5 lb/ft³.
- High-density (4-5 lb/ft³): Heavier, firmer, springs back quickly. Resists liquid saturation better because the cells are smaller and more tightly packed. Tolerates light misting and spot cleaning. Dries more slowly than low-density foam because there's more material holding moisture.
- Mid-density (3-3.5 lb/ft³): The most common orthopedic range. Blot-only for spills; light misting is fine for surface cleaning.
- Low-density (under 3 lb/ft³): Light, compresses easily, drinks liquid fast. Blot-only cleaning is the safe approach. Never mist directly, apply cleaner to the cloth, not the foam.
Infusion Type Changes the Cleaning Rules
Many modern orthopedic beds infuse the foam with gel or copper to manage heat and odor. Each behaves differently around moisture and cleaners.
- Gel-infused memory foam: Contains gel beads or a gel layer for cooling. Gel can be degraded by alcohol-based cleaners and by prolonged soaking. Stick to distilled water, mild detergent, and vinegar. Avoid anything labeled "antibacterial" that lists alcohol or quaternary ammonium compounds.
- Copper-infused memory foam: Copper is antimicrobial by nature, so it needs less aggressive cleaning. The risk is oxidation, copper can discolor if exposed to bleach, ammonia, or acidic cleaners stronger than diluted vinegar. Use the mildest option that works.
- Standard memory foam (no infusion): The most forgiving. Vinegar, baking soda, and mild detergent are all fine.
- Charcoal or graphite-infused foam: Similar to copper, avoid harsh oxidizers. These foams are often darker, so test any cleaner on a hidden corner to check for fading.
Eco-Friendly and Non-Toxic Cleaning Options
For owners sensitive to chemical smells or with dogs that lick the bed, plant-based and food-grade cleaners do the job without leaving residue.
- White vinegar (diluted 1:3 with distilled water): Mild disinfectant and deodorizer. The vinegar smell fades as it dries.
- Baking soda: Absorbs moisture and neutralizes acid-based odors. Sprinkle, wait several hours, vacuum.
- Castile soap (a few drops in distilled water): A mild, plant-oil-based detergent that rinses clean.
- Hydrogen peroxide (3%, diluted 1:1 with water): Useful for biological stains and lightening discoloration. Test first, it can bleach darker fabrics.
- Distilled water: Avoids the mineral deposits in tap water that can leave rings on foam.
- Enzymatic cleaners labeled plant-derived: For urine and other biological fluids, enzyme action beats vinegar. Look for protease and amylase on the label.
Mistakes to Avoid When Cleaning Orthopedic Memory Foam Beds
The biggest mistake is treating memory foam like a regular mattress. These errors cause the most damage:
- Soaking the foam. Liquid saturation feeds mildew and breaks down the foam structure.
- Abrasive scrubbing. It shreds the surface and spreads stains instead of lifting them.
- Machine washing the mattress. Only the cover is washable.
- Direct sunlight drying. UV light weakens foam and fades covers.
- Harsh chemicals. Bleach and ammonia damage foam and can harm your dog.
- Skipping the protector. A waterproof liner is the single best defense against stains and odor.
Conclusion
Deep cleaning a memory foam bed is mostly about restraint: blot instead of soak, air dry instead of rush, and protect the foam before accidents happen. That's the whole method, and it's why we designed the Haven with high-density orthopedic memory foam, a sealed waterproof liner, and a tailored cover that zips off and machine-washes cold. The solid North American hardwood frame is guaranteed for ten years, so the mattress inside is worth protecting.
Frequently Asked Questions
Can you submerge orthopedic memory foam in water?
No. Submerging memory foam beds in water saturates the foam structure and breaks down the cell walls that give the bed its support. The foam can take days to dry and may develop mildew inside. Instead, remove the cover and wash it separately, then spot clean the foam with a barely damp cloth and a small amount of mild detergent. A sealed waterproof liner, like the one on the Haven, prevents liquid from ever reaching the foam core.
What is the best way to deodorize a memory foam dog bed?
Sprinkle a thin layer of baking soda over the foam and let it sit for at least 30 minutes, then vacuum it off with an upholstery attachment. Baking soda pulls out odors without adding moisture. For stronger smells, mix distilled water with white vinegar in a spray bottle, mist lightly, and air dry completely in a well-ventilated room. Avoid direct sunlight, which can degrade the foam over time.
Is it safe to use enzymatic cleaners on memory foam?
Yes, as long as you apply them sparingly and let the foam dry fully afterward. Enzymatic cleaners break down the proteins in urine and other biological fluids, which is why they work better than regular detergent on pet accidents. Spray a light mist rather than soaking the area, blot with a clean cloth, and repeat if needed. A waterproof liner keeps the cleaner from seeping into the foam core.
How often should you deep clean a pet's orthopedic bed?
Wash the cover every one to two weeks if your dog sleeps on the bed daily. Deep clean the foam itself every two to three months, or sooner after accidents, illness, or heavy shedding. Dogs with allergies, skin conditions, or frequent outdoor exposure may need more frequent cleaning. Regular vacuuming between deep cleans keeps debris and dander from working into the foam structure.
