The testing required collecting "oily" residues from a local restaurant for a couple of days. This is the "dirt" that was used in the experiment.

The "oily dirt" was filtered through cheese cloth to remove solids and placed in a shallow pan. A box of microscope slides was then dipped, one slide at a time, into the pan and stood on end to drain.

Several dish pans were filled half way with warm tap water and the recommended amounts of dish washing cleaner was added and mixed well (to point of foaming).

Several slides were dipped into each pan and the times recorded for the "dirt" to be removed from at least part of the slide. Photos were taken.

The extra effort was taking a few dozen dirty slides and "baking" them in an oven at 300 degrees for about 10 or 15 minutes. These were treated like the unbaked slides to see if the cleaner would work.
