Datak says about Tinnit:

"4. After plating, the cirucit board will have chemical residues that will 
in time dull or corrode the plating. To neutralize and remove these 
residues, immerse and scrub the object in a mild solution of household 
ammonia, followed by running water rinse. Dry and polish with a paper 
towel."

FWIW.
