You get up one morning, and it smells like skunk.

After investigating, you realize that your topper is the cause of the bad smell. Immediately, you think that washing it will be an unending task, much to your despair. But in order to have a clear conscience before giving up, you check the scope of work by looking up “how to clean a foam mattress topper?” on Google, and wham! You come across Polysleep's guide on how to easily clean your foam topper. So cheer up and read on. You'll see, it's easy!

“So how do I clean my foam mattress topper?”

No machine, handwash!

What is the answer of the all-knowing search engine? "By hand, of course." You can already see yourself having to remove stains with your nails! But as you read the search results, you understand that it's better to clean your mattress by hand and not by machine. In fact, the lining of your mattress topper could deform, making it uncomfortable and shortening its useful life. Hand washing is therefore preferable if you want to maximize its longevity!

Hand washing your foam mattress topper 101.

Here's a multi-step method that is perfect for removing perspiration, among others, to be done monthly or every two months:

  1. Vacuum your mattress topper at maximum power to remove as many dust mites and their bacterial friends as possible, as well as your dead skin and nail clippings.

  2. While you're at it, repeat this step with the mattress, it will be good for it!

  3. In your bath or a large tub, pour water and the equivalent of a cup of white vinegar.

  4. Immerse your foam mattress topper in the solution. Gently rub it to allow the solution to penetrate.

  5. Let it rest in the mixture for a few minutes.

  6. Rinse it with clean water under the tap. Do not immerse it in a bath of clear water!

  7. Make sure that there are no residues or excess water. However, do not wring it out like a sponge, as this could damage the lining!

  8. Don't hesitate to rinse it a second or even third time if necessary.

  9. Let it dry in the sun. Avoid the dryer, which can damage the lining!
