Trial Purpose:
To evaluate alternatives for a longer cleaning time.
Date Run:
12/02/2004Experiment 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.
