Memory foam mattresses conform to the body shape of the people that sleep on the mattresses. Originally made to help astronauts endure g-forces more comfortably during the lift-off process, a Swedish foam company began to work with the foam in the 1980s in an effort to develop products for consumer use. When mould develops on the surface of your Memory foam mattress, due to prolonged exposure to moisture or humidity, you must promptly and thoroughly remove it to prevent it from spreading further.
Remove linens from the memory foam mattress. Open a window or run an electric fan to help dry the surface of the mattress if there's any moisture.
Vacuum the surface of the memory foam mattress to remove mould spores. Ensure you vacuum the entire surface to remove tiny mould spores that are not visible to the eye. Throw the vacuum bag away in a trash bag to prevent mould spores from transferring elsewhere.
Mix 2 tbsp mild dishwashing detergent with 1 gallon hot water in a bucket. Stir the solution to create frothy soap bubbles on the top. Dip a sponge in the soap suds only and sponge the surface of the memory foam mattress to kill and remove any remaining mould spores.
Dampen a cloth and wring out excess moisture. Blot the mattress surface to rinse off the soap suds. Dry the memory foam mattress surface by pressing a dry cloth into the mattress to absorb moisture. Use the fan or fresh air from an open window to aid in the rest of the drying process.
Spray your memory foam mattress with disinfectant spray to combat any mould spores that might remain and to inhibit further mould development.
As an alternate to sponging the mattress with soap suds, mix 1 cup rubbing alcohol with 1 cup water and blot the surface with the diluted alcohol mixture, instead. Tackle lingering mould and mildew odour on your mattress by sprinkling baking soda over the surface. Allow the baking soda to absorb the odour for several hours before vacuuming it off. Run a dehumidifier in rooms prone to humidity to protect the mattress, furniture and flooring from developing mould.
