When I worked at H-P, the original H-P, Loveland instrument division the
last stage for circuit boards coming off the soldering process was a
trip through a regular home dishwasher with tap water and Calgonite. It
got ionic contamination off the boards better than anything else we

Been a while. Sounds like a reasonable approach with the soap and water.
The key is not to force water into the inductors. I take soapy water and a
tooth brush it works wonders. Then dry in an oven at about 100 degrees just
