Mattresses stored away for weeks or months can accumulate musty odors, settled dust, and hidden stains. A thorough refresh restores freshness, supports better sleep, and extends the mattress’s life. This guide provides a practical, step-by-step approach using common cleaning tools suitable for American homes.
Quick Answer
Start with a quick deodorizing and dry brushing, then tackle stains with enzyme cleaner, freshen with baking-soda-based spray, and finish with a microfiber wipe-down before airing out. Use a handheld vacuum to remove crumbs, a fabric steamer to lift fibers, and a microfiber cloth for gentle scrubbing. Allow ample drying time between steps to avoid mold growth.
What You’ll Need
- Handheld vacuum cleaner for mattresses – for quick debris removal
- Fabric steamer for mattresses and upholstery – to refresh fibers
- Enzyme cleaner for mattress stains – breaks down organic stains
- Mattress deodorizer spray with baking soda – neutralizes odors and dries deodorized foam
- Microfiber cleaning cloths for mattress cleaning – for gentle scrubbing and blotting
Before You Start
Prepare the sleeping area and mattress surface before cleaning. Move the mattress to a well-ventilated space, preferably near a window or with a fan. Protect floors with a drop cloth or old towels. Test cleaners on a small, inconspicuous area to ensure fabric compatibility. Allow extra time for drying, especially in humid climates; plan for a full day if possible. If the mattress has a non-removable cover, follow manufacturer recommendations for cleaners to avoid fabric damage.
Step-By-Step: How To Clean A Mattress That’s Been In Storage
- Remove all bedding and vacuum the surface with the handheld vacuum cleaner for mattresses to pick up dust, dust mites, and crumbs.
- Inspect the mattress for visible stains or dampness. If damp, use a clean cloth to blot; avoid rubbing, which can push stains deeper.
- Lightly steam the surface with the fabric steamer for mattresses and upholstery to lift fibers and reduce odors. Keep the steamer moving to avoid water pooling.
- Apply the enzyme cleaner for mattress stains to any stained areas. Follow the product directions, usually allowing a short contact time before blotting with microfiber cloths.
- Blot the treated areas with microfiber cleaning cloths to remove moisture and loosened residue. Repeat as needed for stubborn stains.
- Spritz the mattress deodorizer spray with baking soda across the entire surface to neutralize odors. Allow the spray to dry completely while the room is well ventilated.
- Brush or pat the surface with microfiber cloths to remove any residual baking soda. Use a light, even touch to prevent fabric thinning.
- Flip or rotate the mattress if possible and repeat the cleaning process on the opposite side to ensure even freshness.
- Let the mattress air dry thoroughly. Use a fan or dehumidifier to accelerate drying, especially in humid spaces.
- Reassess for any lingering smells. If needed, repeat deodorizing spray and allow extra drying time before replacing sheets.
- Place clean bedding back on the mattress and sleep on a dry, refreshed surface.
- Schedule regular maintenance: vacuum monthly, spot-clean stains promptly, and replace or refresh the deodorizer every few weeks for ongoing freshness.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Persistent musty odor after cleaning | Inadequate drying or deep-set moisture | Increase ventilation, run a dehumidifier, reapply deodorizer and steam lightly | Dry thoroughly before sealing in linens |
| Stains reappearing after cleaning | Stain penetrating the foam or cover | Reapply enzyme cleaner and blot with fresh cloth; consider a second application | Act quickly on spills; use protective covers |
| Fabric appears stiff after cleaning | Excess cleaning residue | Blot with clean cloths and inspect for film; re-steam lightly | Use minimal cleaner and rinse with water-safe method |
| Water pooling on surface during steam | Over-wetting or high humidity | Pause and allow to dry; use fans to accelerate drying | Avoid heavy spray; test steamer on a hidden area |
Common Mistakes
- Over-wetting the mattress, which can lead to mold growth
- Using harsh chemical cleaners not designed for mattresses
- Rubbing stains aggressively, pushing them deeper into the fabric
- Skipping drying time, especially in humid environments
Tips For Best Results
- Ventilate well and use a fan to speed up drying between steps
- Test every cleaner in a hidden area before full application
- Apply deodorizer spray evenly and avoid pooling liquids on the surface
- Combine enzyme cleaners with regular vacuuming for best stain removal
- Consider a mattress protector to simplify future cleanups
Call A Professional
Contact a professional if there are signs of mold, persistent odors despite cleaning, or if the mattress has sustained water damage. Seek immediate help if you notice musty smells that intensify after cleaning, or if you have respiratory sensitivities, allergies, or severe staining that won’t respond to consumer products.
FAQ
Is it safe to use a fabric steamer on a memory foam mattress?
Yes, but keep the steamer moving and avoid soaking the foam to prevent water damage.
How often should I clean a mattress stored for a long period?
Once or twice a year is usually sufficient, depending on storage conditions and odor presence.
Can enzyme cleaners damage mattress covers?
Most fabric covers tolerate enzyme cleaners, but test first on a hidden area to prevent discoloration.
Should I remove the mattress cover before cleaning?
Yes, remove any cover to clean both the cover and the mattress surface separately.
Buying Guide
When choosing cleaning tools for a mattress that’s been in storage, consider size, durability, and ease of use. A compact handheld vacuum is ideal for quick cleanups, while a fabric steamer should be gentle enough for foam layers. Look for enzyme cleaners formulated for mattresses and deodorizing sprays that include baking soda for neutralizing odors. For repeated maintenance, microfiber cloths offer a soft, residue-free option. Assess how much you value portability, power, and the ability to work around tight spaces. Consider how often you’ll clean and whether you’ll store the mattress in a humid environment, which may influence drying time and tool selection.
