Spots from Isopropyl

[JunZuloo]

I just cleaned the back of my GPU and soundcard with Isopropyl Alcohol and after letting it dry up I noticed white spots and smudges on them. Do I need to worry about them?

The alcohol probably caught some dirt (or flux, or dust or something) and when it dried off, the stuff got left behind. Try cleaning a smudge with the alcohol but be careful.

I would not recommend cleaning cards like that with liquid. Dry dust, blow it off, can of air maybe, or if you want it really clean, an hour of your time & Q-tips...but liquid to clean a PCB of dust...not something I would do.

I tried air but it was like it was stuck to the card. I've viped it down with a soft brush a second time and it seemed to help. Don't have any Q-tips at home and i need to finish today

Use a air compressor set to no more than 50psi and a fine soft brush and just bruch and blow at the same time!

Oh, it's that kind of dust. Yeah you'll have to get abrasive but I still wouldn't turn to liquid. I'd go out and buy a box of Q-tips. Cheap, a box'll last you forever and gets that sticky dust off.
