Joe 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 to drive off the moisture. Very gentle. I guess the other point is to get a better feel for the gunk. Does soap and water do it. The fact that IPA didn't is interesting. It may be oil based. Good luck Paul WB8TSL/1
