Serta mattresses can become stained and dirty with everyday use. To clean a mattress, remove all sheets, blankets and various other bedding from the Serta mattress so you are left with a bare area to work with. Add an attachment to your vacuum and suck up any surface dirt or other debris that is present on your Serta mattress. The method of removing stains from your mattress depends on the type of stain that is present.
Blot up fresh urine stains with paper towels. Continue blotting until no more urine can be absorbed. Discard the paper towels in the trash.
