Research has shown that the use of Fluorescent markers are the best way of assessing the cleaning process.

See Comparison of Methods for Cleaning Audits

  • The Audit™ marker pen safely and hygienically marks surfaces to be audited with an invisible mark, which will glow bright white when illuminated with UV light.
  •  Marks will be easily removed with normal cleaning methods.
  • After cleaning has been carried out use the Revealite™ UV torch to illuminate the areas that were marked.  Any remaining marks would indicate that cleaning has not been performed effectively.
