What's the best way to...
 

...thoroughly clean a grubby, dusty circuit board, without damaging the board or its components? I've struggled with this task several times in the past, trying everything from a simple toothbrush to the leaf blower, but the particularly stubborn ones never 'come clean', so to speak. I even followed some advice to hose a board off once, though I apparently didn't do it right, as the flyback got wet and shorted. Not doing that again :D

I use super slick stuff and q-tips. thats after useing makeup brush (ask a female) to gently knock dust up, while holding a vacuum hose nearby to suck in the dust.

the super slick stuff has a citrus smell, works well as a cleaner for tube pins and pots as well.

Goo Gone: that stuff will remove ANYTHING.

did you just let the IF and other coils get soaked as well?

:smoke:

I have a similar Truetone in a 19" portable form, it was equally grubby so I pulled the chassis, sprayed it with some Purple Cleaner and used a brush to clean it.
I avoided the power transformer and the flyback area and took care not to wash off the ink stamps.

I let it dry for several days and it was fine.
Put it in the Oven at 150 degrees for a short while if you can, that'll dry out a lot of it.

The I.f.'s are probably wound on plastic forms and everything else is most likely epoxy or rubber coated.

I've even washed 1940's chassis (Flyback and all) in soap and water with no ill effect provided you don't try to power them up too soon.

Is that Super Slick Stuff non-conductive? And do you remove it, or leave it on?
