[Harp-L] Curious about how the group feel about buying used harps and cleanliness

[Tin Lizzie]

I would like to hear more about ultrasonic cleaners.  I have a “household use” one that I bought decades ago, and I would be hard pressed to say that it does more than just buzz for three minutes.

Is there some magic cleaning solution that you have to add?  How about dish detergent?  Brands or types that are known to be effective or bogus?

Does anyone swear by them, or is there maybe some placebo effect going on?  (I’m all for the placebo effect, but I like to know when I’m getting it...)

Vern, you got any science about this for us?
