Testing was conducted using water as the cleaning solvent. The tabletop surface (wood veneer) was pre-cleaned using an activated water cleaning system to enhance the removal of any biological material from the surface.
A baseline reading was taken using a Hygiena System Sure Plus ATP measurement device in conjunction with Ultrasnap ATP test swabs. A four-inch square section of the pre-cleaned table was swabbed and read with the device. A green grape was cut in half and smeared across the surface to supply ATP. Following the application, a swab of the surface was taken to determine the level of ATP on the surface. The surface was sprayed with water and wiped again with each cloth type and a final ATP measurement was made. A second set of cleaning was performed by first using a squeegee then wiping with paper towel.
