[Amps] SB-220 Submerged

[Mark Marsden]

FYI for ultrasonic cleaning here at work we use Electrolube Super Safe
Wash 2000, the chemical name is 2-Aminoethanol (MELA). It's diluted to
2% with 98% deionised water (as used in batteries & steam irons).  It
sure makes electronic assemblies shiny clean. Good luck with the SB-220.

Hi Bill

An amateur friend of mine has a business hiring out PMR radios. As you
can imagine they sometimes come back from hire in a terrible mess having
been dropped into everything you might imagine, the least of which is
dirty water. His solution is to drop them into an industrial ultrasonic
cleaning bath and then, as Gary suggested, oven bake them dry. Over the
years he has "subjected" hundreds of radios to this treatment and,
without fail, if it is done carefully, they work fine afterwards. The
ultrasonic cleaning bath is filled with tap water and a splash of some
commercial additive is added. I can find out what it is if you want.

Other than the obvious "dry it out" what should a guy do to get a SB-220
back on after having been submerged in a basement for over a week?
