I have mentioned several times here that Protek turns green in some 
situations, including when kept in the brass-spouted Schaff container.  
Don, I'll bet your Protek + center pins solution show results in days, 
not years.  My _guess_ is that the reaction with brass comes from the 
solvent in Protek and not the lubricant itself;  I have seen no green 
reaction from Protek in actual use, that is, where the solvent has 
evaporated off.
