Trial #9
To evaluate the effectiveness of various cleaners in removing Masterdraw L240B from aluminum coupons.
There are no related objects.
Four cleaners were tested at room temperature on aluminum coupons to evaluate how Masterdraw L240B soil was cleaned. Preweighed coupons were coated with each supplied soil using a hand held swab for each substrate and weighed a second time to determine the amount of soil added. Each cleaner was put in a beaker and each coupon were placed separately and immersed into the solution for 5 minutes. The coupons were then stood upright to air dry for 15 minutes and then placed on a tray. There was no rinse. Once dry, final weights were recorded and efficiency was calculated for each coupon cleaned.
