This new hygienic
marker is designed to safely and hygienically mark surfaces to be
cleaned, with a harmless, non-toxic invisible coating which only becomes visible
under Ultraviolet light. The audit marks are
easily removed with normal cleaning (even a damp-cloth) so if they remain after cleaning,
it would indicate the surface has not been cleaned effectively.
Suitable for clean, dry
and smooth non-porous surfaces only (except some plastics)
