Trial Number 333

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 05/26/04

Experiment Procedure:
All products were used heated to 96 F on a hot plate in 250 ml beakers. Eighteen preweighed steel coupons were coated with Rochester Midland RI780 rust preventative (80252-41-3, 95-63-6) using a hand held swab. The oil was then heated with a Master Appliance Heat gun at 300 F for 10 minutes. After cooling to room temperature, a second weighing was performed to determine the amount of soil that was added. Three coupons were cleaned in each solution for 5 minutes with minimal stir-bar agitation. After drying, coupons were weighed a final time to determine the cleaning efficiency of each product.
