How often do you wash your clothes? Pillow cases & sheets? Then why haven’t you cleaned your mattress recently? You spend 8 hours a night (if you’re lucky) sleeping on that mattress. What do you think is embedded in it? At minimum, you should vacuum your mattress monthly to remove dead skin cells, dust, dirt and dust mites as well as their eggs and feces. Beyond that, have Pro Clean come out and professionally clean your mattress to remove all the contaminants keeping you awake at night.
