  • Compositions and process for cleaning and finishing hard surfaces
    Patent number: 6017872
    Abstract: Hard surfaces such as tile, metal, glass, etc. typically in hospitality locations can be cleaned to a bright, shiny, residue-free appearance using a process comprising cleaning the surface with a first cleaning composition and removing the resulting cleaner residue with a finish cleaner composition. The finish cleaner composition removes all trace of soil and cleaner from the first step and dries to a bright, shiny, spot-free, streak-free, and film-free appearance without a need for a final wipe step.
