Six cleaners were selected based on vendor supplied information and from the lab’s Effective Tests Conditions Database. Five of the six cleaners were diluted to 5% by volume in 400 mL Pyrex beakers and heated to 130 F on a hot plate. The six cleaner was made into 7.7% mixture and only heated to 105 F as recommended by the vendor. Table 1 lists the cleaners selected and the dilutions used.

Eighteen preweighed coupons were contaminated with vanishing film and weighed again. Three coupons were cleaned in each beaker and cleaned using stir-bar-agitation for five minutes. Coupons were rinsed in 120 F tap water for 30 seconds and dried using a Master Appliance Corp, Hot-air gun model HG-301A for one minute at 500 F. After cooling to room temperature, final weights were recorded and cleaning efficiencies were calculated.

SUBSTRATE MATERIAL: Aluminum Coupons (5052)
CONTAMINANTS: Tuf Draw Vanishing Film 2889 (CAS #: 64741-65-7)
CONTAMINATING PROCESS USED: Coupons were coated using a hand held swab.

All of the cleaners selected removed over 98% of the contaminant from the aluminum coupons.  The highest efficiency was the Oakite Inproclean 3800 at 99.74%.  Table 2 lists the effectiveness of the six cleaners tested.

All six cleaners will be evaluated using the other process contaminant currently involved with manufacturing process.
