Well, I have heard from Mr. Szabo and this is what he had to say about washing the panels:

"It sounds as though your panels are in remarkably good condition, especially considering the abuse they suffered. A good blowing out with compressed air, and/or vacuuming would be a good idea. Although some people have removed their panels and washed them, I don't recommend it. Some folks have had no trouble doing this, but others have destroyed the conductive coating, and I haven't been able to ascertain what makes the difference between success and failure. Therefore, this should be done only as a last resort."

I spent most of the afternoon and evening running around looking for the Boraxo soap I'd decided to use for bathing the panels and ended up having to order it from Amazon. These panels will indeed fit in my bathtub after all. So, for the interim, I begin work on the interfaces. Mr. Szabo sent me some instruction for checking the bias and it looks like I'll need to remove all of the extra capacitance from the interfaces until I have them working properly. I'll also look into the mods that were posted earlier in this thread to see about incorporating them into the MK121 interfaces.

This is all I have to add for now. Until I can come up with some documentation for reconnecting any wires that come free of the panels I'm leaning toward leaving them in the frames because the last thing I want to do is make matters worse than they already are. Plus, as Mr. Szabo recommends above, I should leave washing the panels as a last resort.

For me, once I get the Boraxo, and have secured the proper method for attaching the wires to the panels, then I'm going to give them a bath in the tub using very little soap and, while I have the panels out of the frames, I'll give the grill cloths a good cleaning leaving them to dry in the sun. I won't have sun like that for another week according to local weather reports...

With respect to cleaning the grill cloth, Mr. Szabo recommended simply pulling the fabric from the frames and washing them in Woolite or else simply replace them with new fabric and I'm considering this. My only concern here would be in being able to reinstall the fabric as well as it was originally installed. I'm not sure I can do that - I need to think about how I'd approach this and if anyone has any experience in pulling the fabric and reinstalling it, I'd sure love to hear about your experience and would welcome any tips or suggestions...

More photos to be posted very soon...

Best regards to all,

Luther
