Where I can get glycol that's used as a CRT coolant?
CRT coolant contains ethylene glycol and glycerine, usually in a 70/30 mixture.
It can be purchased from most suppliers of consumer electronics parts like
Tritronics or Andrews, or even MCM.
Ethylene glycol is not itself corrosive at all, but is a very good solvent.
It absorbs moisture from the air and forms a corrosive mixture eventually doing
serious damage to a circuit board. It is not sufficient to simply wipe it off.
It needs to be washed off. Use denatured alcohol or isopropanol. A light
detergent and water can work as well, but takes longer. If you had a leak or a
break, make sure to check everywhere in the projector. You don't want coolant on
any boards!
