Amp shorting out.

[PixelGeek]

Howdy, I need a person that knows their electronics. My Butt Kicker Amplifier is shorting out, likely from an unidentifiable residue, it blew its fuse and made my UPS up go in to protection mode. The residue in picture 1 is like a dust, that has no smell. I haven't been doing any kind of home renovation, and the amp sits on a rubber mat up on a desk, so it's not just regular dust. Pictures 2-4 shows the board after I ran it under some hot water with a brush. And picture 4 shows residue around one of the screws. 

 

Nothing looks blown, I do see some corrosion, but I'm in no way an electrical engineer. I'm just guessing that it has something to do with this residue.

you ran it under hot water?

you dont use water...next time use rubbing alcohol or crc electronics cleaner or similar

 

looking at what i can see it kind of looks like something cooked and the residue is from smoke or residue from what died.

is your area humid? high humidity can cause the smoke or residue to cake also

That's what I figured. Thank you for the conformation. Don't know what could have fried, but I guess that it will forever be a mystery... I know that alcohol would have been better, but it's already dead, I just wanted to clean it to look for corrosion.
