Steps on How to Clean Your Mattress

Step 1: Blot Up Spills Immediately

What do you do after bedwetting, dog or cat pee, vomit, or even a water breaking occurs on your mattress surface? Blot it up as soon as possible! Your sheets only provide a very thin layer of protection, but it will take a little time for liquid to truly soak deep into a mattress so putting down absorbent cotton towels or paper towels depending on the size of the spill should be your immediate reaction.

Continue adding dry absorbent fabrics as the liquid is pulled up, and push down from above to get below the surface of the mattress. It’s amazing how much fluid you can soak up this way, and continue to do this until the materials begin to pull away dry.

Things to remember:

The longer liquid sits on a surface, the further it will absorb into the material. Be sure to try and soak up excess spills as quickly as possible to avoid ruining your mattress.

Step 2: Vacuum

Once the mattress surface is dry to the touch, or if you never had an moisture to contend with, vacuum your mattress using an upholstery attachment. Go over it really well and get into the stitching indentations and around the piping and sides. Take your time with this as this is where you will get an accumulation of dust and allergens that could be causing unknown respiratory issues.

This is also especially important if you have had an outbreak of scabies, or think you may have bedbugs at all. All the little mattress crevices are perfect hiding spots for any critters lurking about and vacuuming thoroughly combined with the correct treatment is very effective in their eradication.

Things to remember:

Vacuuming your mattress should be a regular part of your cleaning routine, plus it doesn’t take very long!

Step 3: Spot Treat Stains

Now you can attack any stains you may have noticed while vacuuming. Even if you have always taken good care of your mattress, this can occur easily- especially after being in storage or after a move.

If you know you are dealing with any sort of bodily fluid or animal pee, I strongly suggest using an enzymatic cleaner. These work different ways depending on which brand you buy, so always be sure to follow instructions.

If you are just trying to get out general dirt or liquid stains, follow whatever spot cleaner directions you have, and follow up with a damp cloth to blot up any leftover cleaner residue and refreshing the surface.

Things to remember:

Stains will void a mattress warranty, so be sure to get at them while they are still fresh to avoid the stain from permanently setting.

Step 4: Deodorize

Even the cleanest looking of mattresses can benefit from this step. Odors lurk in fabrics, but luckily it’s really very simple to deodorize your mattresses by liberally sprinkling a box of baking soda over it.

You’ll want to keep this is place for 12 to 24 hours, so it may be a good night to have a camp out on your living room floor to reap the odor pulling benefits of baking soda. Also, if you can, move your mattress into a sunny window- this will help increase the baking soda’s sanitizing power. Once your time is up, simply vacuum up the loose baking soda.

Things to remember:

The more odoriferous your mattress is, the longer you should allow this step to occur. This is also a good trick for carpet and rug odors.

Step 5 (optional): Air Out if Possible

Sunlight and UVA rays are very effective in sanitizing and refreshing fabrics. If it is possible and not back breaking, consider letting your mattress hang out for a day outside. If you have a trampoline this is the perfect surface to place it upon for airflow, but letting it rest upon a sunny deck, or leaning it up against your house can be just as effective.

Things to remember:

Mattresses can be very heavy and awkward. Do not attempt this step alone to avoid accident or injury, and only do it if it is easy to achieve.

Step 6 (optional): Add a Mattress Protector or Pad

If you haven’t done so already, consider adding a mattress pad or waterproof protector. Many people shun this idea initially because they feel it changes the comfort of their sleeping surface, but many mattress protectors currently on the market do not have this issue at all. Waterproof pads, when cared for correctly, will protect your mattress from a variety of all liquid spills and stains, and are generally easy to clean themselves. Plus they are much less expensive to replace if needed.

Things to remember:

Mattress pads and protectors provide a barrier of protection and will help keep your mattress warranty intact- not to mention make cleanup much easier.
