To evaluate selected products for buffing compound removal.
Date Run:
01/29/2007
Experiment Procedure:
Eight products were selected from the lab's database, www.cleanersolutions.org, based on past testing effectiveness and compatibility with substrates and equipment. Each product was diluted to 5% using DI water in 600 ml beakers. 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:
One product removed over 85% of the buffing compound, while two others removed over 60%. The remaining five products were ineffective. The table lists the amount of buffing compound applied, the amount remaining after cleaning and the efficiency for each coupon cleaned.
