To evaluate the effectiveness of client selected cleaners.
Date Run:
07/17/2000
Experiment Procedure:
All the products were diluted to 5% using DI water in 600 ml beakers. The solutions were heated to 145 F on a hot plate. Preweighed coupons were coated with the listed contaminants and weighed again. Three coupons with one contaminant were submersed into a beaker agitated with a magnetic stir bar. Cleaning lasted for 5 minutes followed by a tap water rinse at 120 F for 30 seconds and finally allowed to dry overnight at room temperature. Final clean weights were measured and cleaning effectiveness was calculated.
