Trial Number 2

Trial Purpose:

To evaluate alternatives for a longer cleaning time.

Date Run:

12/02/2004

Experiment Procedure:

Five products were selected based on test results from the previous trial. Each product was diluted with DI water to vendor suggested concentration. The products were then heated to 130 F on a hot plate.

The pre-contaminated stainless steel coupons were cleaned three coupons per product for another 10 minutes (15 total) using stir bar agitation. Cleaning was followed by a 15 second rinse in a tap water bath at 120 F and air blow off for 30 seconds at room temperature. Once dry, coupons were weighed a third time and efficiencies were calculated for each product tested.

Trial Results:

All five products improved with the additional 10 minutes. The Organic Cleaner/Degreaser removed over 80% of the oil/starch mix. The table below lists the amount of soil added, the amount remaining and the percent removed for each coupon cleaned.
