How to Remove Smells From a Memory Foam Mattress

Updated November 21, 2016

Odours and aromas tend to cling to fabrics. While many items can simply be popped into the washing machine, removing unpleasant odours from a mattress is naturally not quite as straightforward. Lovely as memory foam is to sleep on, the porous nature of the material makes it particularly vulnerable to any lingering scent. Luckily, removing smells from a memory foam mattress is not difficult.

Remove all bed linens from the mattress and allow the mattress to stand, uncovered, for 24 to 48 hours. Exposure to fresh air can help odours to disperse.

Scatter baking soda over the mattress. Use a stiff-bristled brush to spread the baking soda evenly across the surface of the foam and allow the mattress to stand, undisturbed, for 24 hours.

Vacuum the surface of the mattress to remove the baking soda.

Flip the mattress over and treat the other side, sprinkling baking soda over the surface and allowing it to sit once again.

Vacuum the mattress a second time, removing all excess baking soda.

Combine 1/2 cup of distilled white vinegar with 1/2 cup cool water. Mix well and transfer the solution to a spray bottle.

Spray the vinegar solution on the mattress, evenly coating the surface with a light mist.

Allow the mattress to dry completely. If any unpleasant odours remain, repeat the process.
