Hi
I would like to have your advice on cleaning the aquadag coating on my Bush TV22 tube (MW-12-16). The bottom of the tube is spotless, but the top is invariably dirty and dusty. From a small test, I noticed that solvents such as meths or isopropyl alcohol appear to dissolve the coating, so this looks like a clear no no.
What are your suggestions? Dry brushing alone, for instance? Or is there something else that can safely be used?
Thanks!
Helder
