Use extra smarts, not extra sweat, for a quick cleaning session.
Once a month, toss the mattress cover in the wash, then give the top of the mattress a light dusting of baking soda. Leave it when you remake the bed. Over tie it will gradually draw dirt an moisture out of the mattress while eliminating odors. Vaccuum the residue and apply a fresh dusting the next time you change the sheets.
