Here are some before and after pictures of a spot cleaning of some berber carpet in Tampa FL. The spots reappeared after the home owner used a rental carpet cleaning machine. She said the carpet had come clean but these spots returned soon after it had dried. This is a common problem that is the result of over wetting while steam cleaning carpet. At Chem-Dry of Tampa our low moisture carpet cleaning system is designed to eliminate this problem by minimizing moisture while maximizing cleaning power.
