How To Clean Foam Mattress: Simple Steps to Refresh Your Bed
If you’re searching for “How To Clean Foam Mattress”, you’re likely dealing with spills, stains, or just everyday buildup. Foam and memory foam mattresses need a different approach than traditional spring beds, and using the wrong method can damage the material. This guide walks through safe, practical steps to clean a foam mattress and keep it feeling fresh.
What Makes Foam Mattresses Different To Clean?
Foam mattresses are made from porous, absorbent material. This means they can:
- Soak up liquid quickly
- Hold onto odors if spills aren’t cleaned properly
- Be damaged by harsh chemicals or excessive moisture
Because of this, the key to How To Clean Foam Mattress safely is gentle spot cleaning, limited moisture, and thorough drying.
How Do I Do a Basic Surface Clean on a Foam Mattress?
For routine freshening (no major stains):
Strip the bed
Remove all sheets, protectors, and covers. If the cover is removable and washable, follow the care label.Vacuum the surface
Use a hand vacuum or upholstery attachment to remove dust, crumbs, and debris. Move slowly over the whole surface, including sides.Deodorize lightly (optional)
Sprinkle a light layer of baking soda over the mattress surface. Let it sit for 20–60 minutes, then vacuum it up.- This helps absorb lingering odors without soaking the foam.
Let it air out
If possible, leave the mattress uncovered for a few hours in a well-ventilated room.
How To Clean Foam Mattress After a Spill or Fresh Stain?
Step-by-step for fresh liquid spills
Act quickly
The faster you respond, the less the foam absorbs.Blot, don’t rub
- Use clean, dry towels or paper towels.
- Press gently to soak up as much liquid as possible.
- Avoid scrubbing, which can push liquid deeper into the foam.
Use a mild cleaning solution
Mix a small amount of gentle liquid soap with cool or lukewarm water.- Lightly dampen (do not soak) a clean cloth in the solution.
- Blot the stained area, working from the outside in.
Rinse with a damp cloth
Use another cloth slightly dampened with plain water to blot away soap residue. Excess soap can attract more dirt later.Dry thoroughly
- Press dry towels onto the area to remove moisture.
- Allow the mattress to air dry completely before putting bedding back on.
How Do I Remove Common Stains From a Foam Mattress?
Different stains often respond better to slightly different approaches. Always test cleaners on a small, hidden area first.
Light body stains or sweat marks
- Create a mix of mild soap and water.
- Lightly blot with a cloth, then rinse with a damp cloth and dry.
Food or drink stains
- Blot up any remaining liquid or crumbs first.
- Use the same mild soap-and-water solution.
- For lingering discoloration, a small amount of white vinegar diluted in water can sometimes help break down residue. Apply sparingly and blot dry.
Odors that remain after cleaning
- After spot cleaning and drying, lightly sprinkle baking soda over the affected area.
- Let it sit for a few hours, then vacuum thoroughly.
What Should I Avoid When Cleaning a Foam Mattress?
To protect your mattress, avoid these common mistakes:
Do not soak the mattress
Too much water can get trapped inside the foam and be slow to dry.Avoid harsh chemicals
Strong cleaners, bleach, or solvents may damage the foam or its cover.Skip steam cleaning
High heat and heavy moisture can affect foam structure and drying time.No vigorous scrubbing
Scrubbing can tear the foam or spread stains.
How Long Does a Foam Mattress Take To Dry After Cleaning?
Drying time depends on:
- How much moisture was used
- Room temperature
- Airflow and humidity
To speed drying:
- Open windows or use a fan to increase air circulation.
- Keep the mattress in a warm, dry room.
- Ensure the area you cleaned feels completely dry to the touch before putting sheets back on.
If you’re unsure, give it extra time. Sleeping on a damp foam mattress can trap moisture inside, which you want to avoid.
How Often Should I Clean My Foam Mattress?
Regular light maintenance is usually enough:
- Vacuum: Every 1–3 months
- Deodorize with baking soda: As needed
- Spot clean stains: As soon as you notice them
- Wash removable cover: According to its care instructions
Using a mattress protector can help reduce the number of deep cleanings needed.

Can I flip my foam mattress while cleaning?
