Trial Number 1

Trial Purpose:

To evaluate supplied equipment for white board cleaning as compared to conventional products.

Date Run:

08/29/2015

Experiment Procedure:

A black dry erase marker was used to color in three sections of the white board with 4 by 18.5 inches rectangles. The surface of the white board was not aged, but used immediately after soiling.
Each marked region was wiped once with a single pass using a dry bounty paper towel. An intermediate, light contrast and color reading were done on the surface to assess if there was any change from its initial dirty. Then the cleaning product was applied to the contaminated surface with 4 sprays across the whole surface. Thereafter the wet surface was wiped using a fresh bounty paper towel from left to right and in reverse until the whole board is visually clean with most to none black dry eraser mark left on the white board. A second application of cleaner was delivered only if the surface becomes dry during the wipe. Light contrast and color observations were made on the white board to determine how effective the cleaning product was after manual wiping. The procedure was repeated for a total of three sections of the white board. A recorded amount of wipes from left to right and in reverse was counted for with the time it took to finish the whole cleaning process.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

The average difference in light contrast (L) and color was through consistent after the wiping process with the cleaning agent. This shows that the end results are consistently stopped at the same time for each cleaning agent. Overall the most effective cleaning agent would be G and O Cleaner and then Quartet Whiteboard. Both cleaners had the least amount of wipes required to remove most to none of the black dry erase marker from the surface. It took around 5 wipes whereas the whiteboard cleaned with Newell Rubbermaid had an average of 9 wipes.
