Oh no. You just touched a countertop, desk, water dispenser or door handle. Was that surface cleaned recently? Properly? More than ever people are concerned about the cleanliness of surfaces. All kinds of surfaces in many types of environments. How can you know how well your staff are complying with recently enhanced cleaning policies? Now you can see for yourself with the new marX invisible surface marker from Brevis. Just stamp some invisible marX marks onto the relevant surfaces and then examine those surfaces later with a GlowBar LED lamp to see if they were properly wiped clean. Seeing is believing. As President Ronald Reagan was fond of saying: Trust but verify.
Good for over 5000 stampings. Wipes off readily with most cleaning products.
