First Claim
Patent Images
1. A method for evaluating cleaning of a surface, the method comprising:
- applying an amount of indicator material to the surface within a space, the indicator material comprising a water-dispersible fluorescent polymer from polymerization of one or more polymerizable fluorescent monomer units and one or more polymerizable non-fluorescent monomer units and having a weight average molecular weight of 2 to 2000 kDa;
allowing for the surface to be cleaned; and
determining if any of the indicator material remains on the surface by exposing the surface to UV radiation.
