• Clean white cloths or paper towels
• Spray bottle

Deep cleaning, deodorizing, and drying

When a mattress needs more than spot cleaning, deep clean carefully. How to clean a badly stained mattress? Steam cleaning is an option for non-memory-foam mattresses if done sparingly. Memory foam must not be saturated with water or steam.

Deep cleaning steps

4. Apply baking soda across the surface and let sit for hours to absorb odors.

Drying is critical. Any dampness can lead to mold. If the mattress stays damp after 24 hours, repeat drying with fans or move it outdoors on a dry, sunny day when possible.

Prevention and maintenance tips
