How to clean a mattress topper

Step 1: Remove and wash your bedding 

First things first, start by removing and washing all of your bedding, from your sheets to your comforter to your pillowcases. That way, when you re-make your bed, all your bedding will be nice and fresh.

Step 2: Remove the topper from the mattress  

Next, carefully remove the mattress topper from the mattress, placing it on the floor with the topper side facing upwards. If your topper is too heavy to move on your own, make sure to ask a roommate, friend, or partner to help you. 

Step 3: Spray the mattress topper with white vinegar 

To clean the topper, fill a spray bottle with equal parts water and distilled white vinegar and spritz the entire topper with the solution. Leave it to sit for five minutes before carefully blotting the mattress topper with a clean towel. 

Step 4: Sprinkle baking soda over the mattress topper 

The next step is to coat the entire mattress topper in baking soda. Then, once the topper is completely coated, leave it to sit for a minimum of eight hours. The baking soda will help to remove any odors, freshening up the topper. 

Step 5: Vacuum up the baking soda

Once the baking soda has had time to chill and the topper smells fresh, the next step is to vacuum up the powder. 

Step 6: Replace the mattress topper and make the bed

That's it! You can now replace your mattress topper and make your bed.
