How to Clean a Mattress Without Soaking the Foam

Dry methods first

Rotate the mattress if the label allows. Vacuum. That removes skin and dust you would otherwise smear with a wet cloth. Baking soda (about 200 g for a queen) sits in the knit, absorbs odour, and vacuums out. Do not mix baking soda into a paste and rub it into foam; you want powder out, not a crust in.

Sun helps. Two hours of direct light on a dry day is a legitimate deodoriser. Do not leave a foam mattress out in dew.

Stains: enzyme, then patience

Blood, sweat, urine: cold water blot, enzyme product, blot, fan. Hydrogen peroxide 3% can lift blood on a light knit — test a corner. Chlorine bleach on a mattress is how you yellow foam and void a warranty. If the core is wet more than 2 cm down, you need air movement for 24 hours, not a fitted sheet at hour three.

• Vacuum both sides and the piping
• Enzyme on protein; blot, do not flood
• 200 g baking soda, 2–4 h, vacuum
• Steam only if the construction is sprung and will dry; skip on solid foam
• If sag plus stain plus smell: replace, do not perfume

Prevention is a $50 cover

A washable protector, sheets on the weekly sheet clock, pillows on their own wash — how to wash pillows — and you might deep-clean a mattress once a year as theatre. Without a protector, every summer is this section again.
