I have just purchased some new whistles that have a peculiar taste, & am wondering what to use to disinfect them.
On my harmonicas, I have used ordinary household disinfectant without any adverse effects, but I’m not sure if it will be OK on these mouth pieces, not knowing what they are made of - the whistles are Generation Nickel.
(Note: It is only these 3 that I have received recently that have this peculiar taste - all my others are fine.)
I’ve never tried it myself but I did buy a second hand whistle from ebay where the seller told me he had cleaned it using Miltons Fluid. That’s the stuff that is used on babies bottles ect. That would certainly be safe to put in your mouth afterwards and the whistle was fine when I got it.
I once saw a guy in Naples cleaning whistles with the steam jet on an espresso machine.
Dunk it in Listerine - it will be “minty fresh” and sanitary!

I’ve always used 99% Isopropyl Alcohol. It hasn’t damaged any plastic or wood so far.
Thanks for your quick responses & recommendations, fellas.
I didn’t want to damage the plastic, so it looks like anything that doesn’t harm or kill us should be OK to use. 
Milton’s is a weak bleach solution. Make sure to rinse well. I guess it should be obvious that any physical crud should be removed before disinfecting. It doesn’t do any good to just swish forty years worth of encromulated organic matter!
Also, if your whistle is sterling or silver plated, don’t use bleach at all! It will turn your whistle black.
Thanks, I haven’t progressed to any expensive whistles (yet?), these were just(?) (new) Generation whistles that arrived with a strange ‘taste’.
I actually used a denture cleaner tablet, (which my sister uses to clean her flower vases), on them, & all seems to be well now, no strange taste.
