Yeah, there's that, but I'd like to do it myself...

On cleaning the woofer panels -

David Janzsen mentions using diluted ammonia WITHout any detergents, and I assume a distilled water rinse so nothing is left that can conduct, and then drying in a closed container with desiccant -
So far with the exception of science / chemical supply houses, all of eh ammonia I can find has detergents / surficants in it -

Any tips or experience would be most welcome.

See if you can find SEMI grade.
this will be pure stuff and come with anallysis certificate.
Unfortunately, NH3 is a GAS and to find it as a liquid, it must be 'mixed' in some fashion. Water would be the most common dilutant but I'm not certain of concentrations available. Or what the maximum solubility IN water would be, which limits the concentration.
Any 'liquid' Amonia will be such a concoction.
Ask Janzsen just what he recommends as a brand name and if some of those 'impurities' would be OK.
The LIQUID form is called Amonium Hydroxide and is nasty. Use ONLY in extremely well ventilated places. I'd wear an Eye Shield (not just safety glasses), a full apron and past-the-elbow GLOVES. I believe the maximum concentration is about 30% or maybe 40%.
Not comfortable working with stuff like that? Leave it to the professionals.
I have trouble finding pure Isopropol Alcohol and Hydrogen Peroxide over 3%.
Too much is never enough
