Q.   I have stains that go away after carpet cleaning, but they return a few days later.   Most recurring spots or stains can be traced to inadequate rinsing of spot removal (carpet stain removal) agents. Many commercially available spot removal (carpet stain removal) agents do an excellent job in removing spills but detergent residues remain behind to attract additional soil. In using any spot removal (carpet stain removal) agent, continue rinsing with warm water and blotting with paper towels until all sudsing has stopped.   Sr. Comments Posted Date
