I never had problems with Coke/Pepsi products, coffee stains (unless there may have been a additive), grease, etc...
What is most interesting however, and unusual perhaps, is a few markings from the sole of shoes! I could clean the carpeting which looked terrific, but would leave a slight marking from the sole. My question for myself (and others reading) is how would you pre-treat this situation?
