I just can't win this week--might just give up computers

So I'm in the process of cleaning up a motherboard and I'm using my favorite cleaner 90% Iso Alcohol

used my trusty canned air to get the bigger things and was wipping off a few things with the iso

I noticed that somehow there was a tiny smidge of AS5 on a corner of the back side and used some of the alcohol to clean that off

but...

after the alcohol dried up there was a noticeable amount of white junk on there --- not AS5 but stuff that almost looked like oxidized material

yes I had taken out the battery and this board has been with out power for some time

I've used water to clean boards before and just made sure they dried off for a few days (haven't done that for a long time) but never ran across this issue with alcohol

if anyone has had any experience with pulling a dumb move like this as well and has some insight about what I did and if I just ruined a board

please help --

I've gotten alcohol on powered electronics before. Pure alcohol isn't conductive, so theoretically it should be fine, even though you only used 90%. Clean off the white stuff, let it dry, and try it out?

I got a large % of the white stuff off using a little bit of distilled water and a toothbrush

I let it dry over night and 80% of the white junk is gone -- i'm going to repeat and see about testing out
