Description
Used to demonstrate proper surface cleaning and the spread of “germs.” Sprinkle the powder on the surface to be tested and smear it around the test area. Follow with normal surface cleaning and then view the surface area under ultraviolet light for remaining “germs.” Each 4-oz container is good for many cleanings since only a small amount is used each time.
CAUTION: UV light can cause damage to the eyes if looked at directly. It should only be used to indirectly observe the effectiveness of this test.
