Before the invention of foam mattresses, innerspring mattresses required plenty of upkeep–including regular intervals of mattress flipping, rotating, and turning. Who has the time to remember to maintain your mattress, much less the muscle required to heave the hefty thing around the room?

When it comes to your foam mattress, ownership is extremely low maintenance. Though regular cleanings aren’t necessary and a mattress cover can best protect your investment, you may wish to routinely freshen up your foam mattress a few times a year. Here’s how:

For a routine cleaning: While it’s best to protect your mattress with a machine washable cover that can be easily tossed in with your sheets, there may be a time that you’d like to deep clean the mattress itself. To do so, grab a powerful vacuum, and start suctioning the mattress, making sure to cover the surface area entirely. If you’d like to freshen up the scent of your mattress, apply a light layer of baking soda, allow it to sit for at least 20 minutes, and vacuum again to remove.

To treat stains: While it may seem appealing to pull out the bleach or ammonia for a feeling of full sanitization, you should never use such harsh chemicals as they could damage the mattress cover as well as the memory foam. (Not to mention the damage they can cause to the environment! According to The Guardian, bleach is from the “organochlorine family of chemicals, compounds rarely found in nature and which can take centuries to decompose.”) Instead, spot clean the stain with a mild detergent and cold water before letting it air dry. For a truly inexpensive, non-toxic and biodegradable cleaning experience, use distilled white vinegar on tough stains. The acetic acid content in ordinary household vinegar has been proven to work as a disinfectant with the power to kill bacteria!

To remove urine: If the urine is still wet, gently blot with towels immediately to absorb as much of the liquid as possible. But, be very careful not to push the urine into the deeper layers of the foam, only apply gentle pressure! Next, soak the urine stained area with distilled white vinegar, and let the vinegar work to break up the stain for between 5-10 minutes. Use fresh towels to blot the area a second time, and then apply a generous amount of baking soda to the area. Allow the baking soda to sit for as long as you can–at least 2-3 hours. Once dry, vacuum up the baking soda, and you’re good as new!
