Hi David It is my opinion that the contamination is in the wood not just in the old cloth. The contaminant usually , as you know , causes the wood to be quite discolored and waxy looking. I have repined an entire set of flanges on a nice old L(mine) once and within less than a year they were just as tight as before. Yes treated them with pro-tek and within months the creeping green scourge returned. And definitely not cost effective. Oh yes and have also tried perchlorethelene(dry cleaning fluid) and that as well is temporary. So there you have it,the readers digest condensed version of verdigris removal made expensive and difficult. I've been round the verdigris cure race track plenty and it's a race none yet can win Really though ,what a waste of originally fabulous materials. If I really wanted to make money I'd find a real scientific cure for this malady and retire from the rebuilding business,or, well at least I'd hopefully be more popular with some.
