Most people probably don’t consider cleaning their entire mattress. It is a large and cumbersome thing, and its not like you can put it in the washing machine. However, there are some things you can do to clean and freshen it up.
1) Rotate your mattress every six months or year to keep the padding impact and foam use even across the mattress. If you have a pillow top mattress, you can only rotate your mattress 180 degrees. But if you have a standard mattress, you can rotate as well as flip the mattress over.
2) To cut down on the potential for stains, use a waterproof mattress pad and wash it regularly with your sheets in a washing machine. Look for a mattress pad that is waterproof and stops dust and dust mites.
4) Vacuum the top of your mattress. This will actually suck out most of the dust mites and nasty dust mite leftovers (corpses and poop). Make sure that the nozzle of your vacuum cleaner is clean and slowly vacuum all of the crevices and the surface to eliminate the little buggers. Its kind of nasty but this is a major step in cleaning your mattress. If you use a waterproof, sealed mattress pad this is a quick and easy step.
5) If your mattress smells like hobos have been sleeping on it, you can sprinkle about a 1/4 cup of baking soda that has been mixed with 2-3 drops of your favorite essential oils (lavender is a great choice) all over the surface of your mattress. Let this sit for about 30 minutes and vacuum it up with a clean hose attachment or nozzle on your vacuum cleaner.
