Trial Purpose:
To evaluate semi-aqueous products in an attempt to increase cleaning times.
Date Run:
03/08/2007Experiment Procedure:
Eight products were selected from the lab's database, www.cleanersolutions.org, based on past testing effectiveness and compatibility with substrates and equipment. Four products were diluted to 10% using DI water in 600 ml beakers and the other four were used at full strength. Each solution was heated to 130 F on a hot plate.
Twenty-four preweighed coupons were coated with Jackonslea Grey Color 305 A (1344-28-1) by heating the buffing compound to facilitate transfer to the stainless-steel coupons. Once cooled, coupons were weighed again to determine the amount of buffing compound applied. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. Coupons were rinsed for 15 seconds in 120 F tap water and dried using compressed air at room temperature for 30 seconds. Coupons were weighed a third time to determine the amount of soil remaining and efficiencies were calculated for each coupon cleaned.
Trial Results:
Seven of the eight products removed over 85% of the buffing compound within 5 minutes of immersion cleaning. Four of these removed over 94%. The table lists the amount of buffing compound applied, the amount remaining after cleaning and the efficiency 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 seven effective products will be tested at shorter times using ultrasonic energy.
