As a general overview on our product system, we have a single concentrated product that is used to clean 95% of the general daily facility cleaning. It is not intended to be a super heavy duty cleaning product, which we feel is over kill in most situations. Please keep that in mind for our requests and beliefs regarding soil load. The product is used at two dilutions; heavy duty which is for heavy soils and sanitizing. Light duty, which is used for glass/mirror cleaning, floor cleaning, and general surface wipe down. Residue build up is big part of our value proposition and due to that we really need to develop a testing methodology.
