Spot cleaning of stains

Spot cleaning of stains on the topper will need some extra efforts. Use vinegar and baking soda to get rid of these stubborn stains on your topper.

Vinegar and water solution

Place the mattress topper on a flat surface and vacuum it. Make a solution of two parts vinegar and one part water. Rub this mixture on the stain to clean it thoroughly.

Clean the vinegar with a damp towel and dry it with a dry one.

Baking soda mixture

Baking soda mixed with water is another perfect solution for removing tough stains. Mix one part of soda with two parts of water and stir it till baking soda dissolves and turns milky.

Rub this mixture on the stain and the area around till you can get as much stain out as possible. Leave the mixture for half an hour and then cream it with a damp cloth or towel.

Use a dry cloth to blot out the excess water from the mattress topper.

Removing odors from mattress toppers

Some smell like urine, vomit, and cigarette can be challenging to remove. To remove these odors vacuum and spot clean the mattress as mentioned above.

Then sprinkle the mattress with some baking soda. Let it stay for at least eight hours and then vacuum.

You can also clean with citrus based cleaning products that are available in the market as they are beneficial in removing odors.

You can also expose the mattress topper to direct sunlight for a short period as it can help eliminate most odors.

Cleaning the complete mattress topper

While vacuuming once a week is good and spot cleaning any spills and stains is essential, you must also wash the entire mattress topper thoroughly every few months.

For this spray the whole topper with a detergent solution. Don’t spray the entire mattress together. Spray the detergent solution on small sections at a time and gently rub with a soft cloth or towel in a circular motion.


Once the complete topper has been cleaned, use the spray bottle to rinse it with cold water. Dab the excess water with towels.

Roll the topper inwards gently to remove the excess water. Do not squeeze. Unroll the topper and let it dry before you use it.

Drying memory foam mattress topper

You must dry the mattress topper thoroughly before you use it to prevent mildew. Leave the mattress to dry under shade for at least eight hours. Use a fan or a dryer to help dry up the mattress topper faster.
