Abstract
Fluorescing gel formulations are disclosed for monitoring cleaning of a surface. The fluorescing gel formulations are stable, fluoresce under UV light, and do not leave a mark after drying and removal. The compositions include an oppositely charged complexing agent which is used in combination with an anionic or cationic optical brightener. In some embodiments, the compositions include a cationic optical brightener with no complexing agent.
