Trial Number 11

Trial Purpose:

Laboratory evaluations of alternative cleaning products

Date Run:


Experiment Procedure:

Two products were diluted to 5% and heated to 130 F. Copper coupons were coated with a coating and an ink.

Trial Results:

The black dye may be pulling off some copper during immersion.  These two products don't react with copper.  No signs of corrosion were detected visually.

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.


Mostly successful in removing the ink. Some mixed results on the coating.
