What solution do you use in an ultrasonic cleaner?

[nick0123]

Just (finally) got an ultrasonic cleaner for bracelets, end pieces, clasps etc.

Wondering what solutions are best for the actual cleaning — dish soap, isopropyl alcohol, Cousins Jewellery Cleaner, carburettor cleaner etc?

Thanks!

I use hot water with a few drops of dish soap, worked well so far.
