The purpose of the experiment was to determine if a low pressure parts washer would be effective in removing the contaminant from the coupons.

Coupons were contaminated in the same way as the previous trials. A Miele low pressure(15psi) parts washer was used in conjunction with cleaning chemistry designed for such a system. The coupons were loaded into the washer in a way to maximize the use of the spraying. To do this, the coupons were clipped upside down to the sides of the pull out tray. The powder cleaner was deposited into the washer. The cleaning, rinsing and drying cycle lasted for about thirty minutes. The operating temperature was between 170 and 180 F.

The low pressure washing of the coupons were very effective in removing the grease from the stainless steel coupons.

Evaluation of three different types of equipment has resulted in the identification of one effective system.  Low pressure spray washing removed a majority of the grease.
