Trial Purpose:
To evaluate alternative cleaning products for removing cotton seed oil/starch mix.
Date Run:
12/01/2004Experiment Procedure:
Six products were selected from the laboratory's database of test results and vendor supplied information based on client specific needs. Each product was diluted with DI water to vendor suggested concentration. The products were then heated to 130 F on a hot plate.
Eighteen preweighed stainless steel coupons were coated with the supplied cotton seed oil/starch mix and allowed to sit for 24 hours. Coupons were then weighed a second time to determine the amount of soil that was added. Three coupons were cleaned in each product for five minutes 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:
Five of the six products consistently removed over 90% of the cotton seed oil/starch mix. 1St EnviroSafety's Ecco Commercial cleaner removed over 98% of the oil in the five minutes of cleaning at 130 F. The table below lists the amount of soil added, the amount remaining and the percent removed for each coupon cleaned.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
The five effective cleaners will be tested on the coupons that have been contaminated at the client's site in their processing equipment.
