I use this regularly on my plastic and plastic-headed whistles that have a tendency to clog, but has anyone tried it on different materials? Is it safe to use on brass or copper, for instance? Delrin? What about sealed hardwood (such as an Elfsong fipple)?
For much of the world, winter is a drying season, but here it’s wet (VERY wet!), and I’m getting more clogging than usual, even with whistles that (normally) rarely clog.
The soapy water treatment is safe to use (and should work) on all metals, Delrin or sealed wood. I wouldn’t use it on unsealed wood, however, but unsealed wood isn’t as likely to clog in the first place.
I use it on my whistles. There is a small slip of unsealed wood on either side of the windway which does not seem to be a problem. I do this on all of my wooden recorders too which have entirely unsealed windways and have never had a problem-- recorder players do this all the time.
You don’t need a LOT of soap. Couple of drops of Dawn in an ounce of water is plenty.
That’s a relief, Paul. I’ve been using it on some of my wooden ones, especially the ones with metal in the mouthpieces. I also recently resorted to it with a Bleazey blackwood that I’ve always had clogging problems with. If that doesn’t do the trick, I’ll try the Grinter technique of soaking the whole mouthpiece in oil.
