@TheAstroChuck Sure it does. I've used whistles (and reeds) - I play bassoon/ sax etc. that would never pass the sniff test that perform perfectly well. In Jr. High I worked in the cateria and was alwasy given food after lunch was over so wound up running to band (the next class) while chewing food. From first hand expereince, I can assure you whistles and reeded instruments perform well when totally crudded out.

@TheAstroChuck I've used similar stinky (not clean) whistles (about 1.5 inch in size) many times without any performance issues.

@TheAstroChuck You're good.
