Effective Electronics Circuit Board Washdown?
For a Meanwell. Not that it matters but it's for a 36-volt 400-watt power supply. Blew a fuse. Incredibly dusty circuit board. I'll blow it out with 120 air then wash it. I would like to use something...

Cleaning a dusty looking circuit can also be very helpful as you may already have done. No need to wash circuit, just use a brush and light compressed air to remove all signs of dust from components and between components. There could be a problem called crystalline growth on circuit boards(in amoungst the dust) and we did see this at times, though sometimes with the aid of a microscope. Crystalline growth can cause a short circuit on the board. A dust free circuit board may also operate cooler. Best of luck. See info on link & Google for images & other info on this:
