I heard or read that it's mostly dust and dirt on the strings that accelerate rusting. This was said I think by Don Mannino in one of his classes. Marcel Barbara - that sounds like something my mother would have said. ;-) Well sure, dirt will attract moisture if the moisture content of the dirt is lower than the equilibrium point between it and the surrounding atmosphere or whatever it is laying on. And it would retain moisture, just like a soundboard or a key or felt or leather or a wool string cover. What that statement suggests to me is that the author is claiming that the presence of dirt on a soundboard will increase the moisture content of the soundboard. I just ain't so. And I was a scientist in another life - so back off baby! ;-) Terry Farrell On Mar 10, 2010, at 1:44 PM, Barbara Richmond wrote: > I heard a technician claim that dirt attracted (or retained) > moisture, so it should be cleaned up from where ever. > > Does it?
