I have one female who is a musker too. Everything in her tub is spot in, as she's in a rack system with 16 other corns who are always on their best behavior.
This is what I use, it's homemade hand scrub I usually use before painting my nails but I noticed it gets the musk smell right out.
Get a little sealable container. Put in a big spoonful of white sugar, cover the sugar in olive oil, and then use one single drop of tea tree oil. ONLY ONE DROP I'm telling you or else it will dry out your hands. Spoon a bit of the sugar/oil into your hand, scrub it around for a minute or so, rinse, and then maybe wash to get the olive oil residue off.
Your hands will feel smoother than a babies bottom and hopefully they won't stink!
