Let’s define the difference between a spot and a stain: Spot– is any foreign material (soil, liquid, etc.) that is removable by standard cleaning methods. Stain– is foreign material (soil, liquid, etc.) on the carpet that is not usually removed by standard cleaning methods. (The foreign material has penetrated or “soaked into” the fiber and has altered the color or damaged the fiber). Some stains may be difficult or impossible to remove. Our technicians are trained and qualified to examine stains to let you know which ones will come out and which won’t.  They will then do everything they can to try to correct the problem.
