Trial Number 9

Trial Purpose:

To evaluate the effectiveness of various cleaners in removing Masterdraw L240B from aluminum coupons.

Date Run:


Experiment Procedure:

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.
