Trial Number 1

Trial Purpose:

To evaluate successful products on client soiled coupons

Date Run:


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.

Fifteen preweighed, pre-contaminated stainless steel coupons were 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:

Three of the five products showed some signs of removing the cotton seed oil/starch mix within 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.
