Our recommendation on this front is to use non-abrasive detergents and if possible more natural approaches such as baking soda.
Natural spray solution
Fill a spray bottle with half water and distilled vinegar. Lightly spray and blot stain with paper towels. You can also use a toothbrush to gently scrub as well. The goal is to not ruin the fibres by using abrasive methods.
Baking soda
As mentioned above, lightly spray stain mattress topper surface with water. Then layer on a thin coating baking soda and gently massage into surface. Allow it to sit for half an hour and then use a vacuum to remove the mixture. You can then use an odor removing solution like above as a final step after the baking soda has removed most of the stain.
Can you machine wash a memory foam topper?
No. Please avoid doing this. One the casing most likely will get damaged from the washing machine and two the memory foam core should never be fully submerged in a washing machine. To even fit one into a washing machine will be a mission in itself which would most likely damage the structure.
How often should you clean a mattress topper?
Our recommendation is to clean your mattress topper two to three times a year. Sleep Foundation also supports this recommendation. Whether this be airing it out and giving it a quick vacuum while you are washing your bed sheets. But in terms of giving it a proper clean, this will depend on your topper. If you have a removable case, then cleaning that every month or so should be adequate. If you have an all in one unit, then a good rule of thumb is giving it a good clean with each season.
How long does a mattress topper last?
A mattress topper can last from a year to 5 years depending on the type and its quality. A memory foam mattress topper will typically last 3 to 5 years. A cheap polyester topper might only last a year before it starts to get a bit funky and lose its integrity.
