[Hallicrafters] {Collins} The best way to clean a Collins board?

[Raymond Cote]

WHAT WERE THE RECOMMENDATIONS FOR CLEANING?  
I saw very little on this topic posted to the group and many of us have Collins gear. Perhaps the default "reply" should be to ALL unless sp ecocide recipient is selected.  I miss over half of the answers to questions I am interested in.

>>> I need to clean the surface of the board (where the tubes are located) of my recently acquired KWM-2 which was on storage for years from the previous owner.
>>> Dust for years has accumulated on the chassis and has stick there with the help of humidity, not coming out even with compressed air. Have used a brush but same thing. 
>>> I need something more aggressive
>>> Underneath the aluminum chassis, where the point to point wiring is located, everything is very clean so no need to clean that much in there.
>>> I'm new to Collins as you all know so have decided to ask first.
>>> 
>>> Have seen a YouTube video of a guy who takes advantage of the fact the radio chassis is aluminum, so he washes it whit a hose and Simple Green, but that is too extreme for a newcomer as that approach will require deep re-alignment (we do have Simple Green here in YS too).
>>> 
>>> What have you used or would recommend? 
>>> Will do the same with the VFO and the 30L-1.
>>> Just received the first capacitors to rebuild the Power supply. Still missing the 0.05uF cap.
>>> The 30L-1 will need a rebuild kit too.
>>> So, I'm having fun fixing this beauty back to operation step by step. :)
>>> Love to work on my radio!
