varney Posted February 14, 2020 Share Posted February 14, 2020 I've had a metal ended Crabb concertina brought to me which I suspect may be suffering the effects of corrosive sweat from the player's hands. I saw this instrument a couple of years ago just before it's current owner obtained it and the ends were in nice condition with just the typical wear you'd expect to see on a vintage instrument. The nickel ends and buttons now have a slight green hue all over and a rough dry feel to the surface almost like a very fine sandpaper. More of a problem is the fact that this corrosion seens to have infiltrated to the reeds with many of the brass shoes coated in verdigris and some tongues displaying surface rust. I'm not fully sure that sweaty hands could have this effect on the reeds so perhaps I'm wrong. I'm just wondering if anyone else has had experience of this or found a way to cope with the ongoing problem? I'd imagine giving the instrument a wipe with a soft cloth after playing would certainly help but if there's any better approach I'd appreciate hearing details. Michael.
