Sample
Remove the plunger portion of the device and place the end with the pad on the surface to be tested. To sample, crisscross a 4 x 4 inch (10 x 10 cm) portion of the surface.

Activate
Return the plunger to the cartridge and activate by pressing it fully into the cartridge. Gently swirl the cartridge for ten seconds.

Interpret
Read by examining the color of the remaining solution using the provided color comparator.

AccuClean Advanced system contains reagents housed in a fully self-contained cartridge that once activated, changes color to indicate the relative level of protein detected on a sampled surface.

After 10 seconds, the remaining solution is then compared to a color comparison chart for interpretation. If no protein is detected, the solution in the bottom of the cup will remain copper-colored to indicate the surface is clean. A color change to gray indicates low level protein has been detected, while a change to green/blue or blue indicates a higher level of protein detected.
