I use pipecleaners
to clean the windways of my whistles.
Of course I use the kind without bristles,
however the end of these pipecleaners
is sharp metal (the wire that
forms the cleaner’s core) and can cause scratches, I’ve found.
There is a material called Pelon which is a stiffener for collars and is available from fabric shops. I cut this material in 1/2 inch wide strips about 3 inches long and use it to clean the airway. Works great!!!
Not to cause to much ado by getting to the original post, but I use 2 methods to clean whistle airways. If something tough is there, I use a narrow strip of plastic cut from an old credit card to “scrape” it out. The plastic is softer than metal or hard plastic mouthpieces, but I’m careful with softer ones such as Generation.
My more gentle method which I use once a week or so is to take a piece of cloth ribbon (1/4" wide) about 8 inches long and feed it through the windway. Wet it under a faucet, and then “floss” it back and forth. Works great and won’t damage the most sensitive of whistles.
Depending on the whistle, a thin, wooden coffee stirrer, (I like the ones from Starbucks the best) works well. Scrapes it clean, burnishes away the crud and absorbes moisture. What more could you ask for…
