A mattress rarely looks dirty, which is exactly why it's so often skipped — but it collects dead skin, dust mites, and years of accumulated dander that a fitted sheet doesn't stop.
Start with Vacuuming
Using an upholstery attachment, vacuum the entire surface, paying close attention to seams and tufts where dust and mites collect most.
Deodorizing
Sprinkle baking soda over the whole surface and let it sit for at least an hour — it absorbs both moisture and odor. Vacuum it up thoroughly afterward.
Treating Stains
Mix water, a small amount of white vinegar, and a little laundry detergent, then spray and blot — never soak — the stained area. The goal is to dampen the surface, not saturate the mattress underneath.
Reducing Dust Mites
Heat is what actually kills dust mites. A fabric steamer set above 200°F (100°C) reaches temperatures hot enough to eliminate mites and bacteria on the surface. Washing all bedding weekly in hot water handles the rest of the ecosystem mites depend on.
How Often
Once every 3 to 6 months for a full clean, with weekly bedding washes in between. If allergies are a factor in your home, pairing this with a broader residential deep clean — including carpets, which trap the same allergens — makes the biggest overall difference.
