[ARC5] [Milsurplus] Cleaning fine crackle paint

[hwhall at compuserve.com]

 Thanks to all for all of the discussions and ideas. 

I should clarify that the item I'm concerned with is not a cabinet/case but a steel chassis with fine black crackle paint and all the components (switches, knobs, indicator lamps, transformer, chokes, capacitor can, tube sockets) mounted on the chassis. So, I guess I ought to be wary of strong soap and other chemicals, because I don't wish to strip the parts off. 

I think I see that one of my problems is that the toothbrush doesn't have fine enough bristles so I'll add a paintbrush to the my tools. There is some oily dirt from a mechanical automatic keyer that I'll need to use some degreasing action on but there are few screws or components nearby that to worry about. And I should expect to have to treat the paint (oil or wax) after all cleaning since I may not get all the fine dust out of the crackle & it will make the paint appear faded if untreated.

Thanks & 73,
Wayne

I'm sure this has been covered but probably long ago... What are some good
techniques for cleaning old, fine dirt & dust from fine grained black crackle
paint? I've tried dish soap, warm water & toothbrush but it seems every time it
the paint dries there is still light colored dirt in the crackles.

Thanks &
73,
