If you think about it, a soiled surface is simply a surface with so many spots that they just run together to form an overall soiled appearance. Traffic lanes on carpets or soiled chair arms are an excellent example of serious spotting problems. A spot is defined simply as soil that can be removed. A stain is defined simply as a permanent change or damage to the soiled area that is not correctable. However, today we have remarkable specialty products and tools that are causing more and more stains to be reclassified as removable spots!! This department focuses on these areas.
