To find a cleaning solution that could remove the Soy Gold film.
Three chemistries were tested at 5% concentrations. Each chemistry was heated to 100 F on a hot plate. Samples were put into each cleaner for 1 minute using a manual agitation (moving coupon back and forth in beaker). Samples were removed and rinsed in tap water at room temperature. Parts were dried using a Master Appliance Corp. Hot-air gun model HG-301A. Samples were observed for any remaining residue by touching the surface.
SUBSTRATE MATERIAL: Aluminum Name plates.
CONTAMINANTS: AG Environmental Soy Gold 2000.
The amount of residue remaining on the coupons was far less than without the aqueous cleaner rinsing, but there was a definite film left on the surface.
Success Rating:A follow up test, usually based on company input.
Additional testing will be conducted using a diluted Soy Gold Solution along with other aqueous cleaners and rinse aids.
