Trial #9
Laboratory evaluations of alternative cleaning products
There are no related objects.
One product was diluted to 5% and heated to 130 F. Copper coupons were coated with a buffing compound, Quaker Slush Coating and a Steel Blue ink (67-63-0, 123-86-4, 71-36-3, 7004-70-0)
While solutions seemed to do something more than the 2%, the efficiencies are quite low.
No success on any of the contaminants
No relation
