To evaluate the efficiency of a product for cleaning window surfaces
Date Run:
09/01/2015
Experiment Procedure:
One 30”X40” section of window was marked off as a testing surface. To the surface, 5 grams of AATC was mixed in 400 ml water to create a soil solution. The mixture was applied by taking a paint roller and soaking it in the soil solution and then swiping the paint roller on the window surface 25 times. The soiled surface was allowed to dry for 20 minutes. Once the soil was dry, testing took place for all the cleaning tools in way that they would be used in real world conditions. For the first round of testing the participants were told to clean the window fully till no trace of soil could be found, they were not instructed on how to use the tools and were timed during their performance. When they were done with one window that window was cleaned and soiled for the next test in that round. For the second round of testing we performed similar analysis, but the test was run with the participants following manufacturer instructions for the paper towels and the microfiber pad. The microfiber towel was not run again. All evaluations are based on a time performance.
