Think of how much time you spend in your bed. Yet, you probably clean the top of your fridge more often than your mattress. Your mattress harbors millions of dust mites, which cause various respiratory conditions including sneezing, a runny nose, itchy eyes, and skin rashes (not to mention just being plain gross).
Disgusting dust mite food is human skin scales, so the bed is just heaven for them.
Use a vapor steam cleaner to root out the itchy devils, then wrapping it in an anti-allergen mattress protector.
At the very least, sprinkle your mattress with baking soda and let it sit for awhile. Then vacuum it up using your vacuum attachment.
If you know of someone looking to buy or sell, give me a call.
