Has anyone seen something like this on a motherboard after letting it dry from the alcohol treatment?
All I have is 91% at the moment due to a few things that keep popping up here and there and I'm out of DeoxIt D5. I know 99.9% is better, but hard to find at Microcenter, but easy to find on Amazon.
I did use baking soda, some 91% Isopropyl Alcohol, and a toothbrush to scrub those areas and it looks a bit better than the picture above.
The dust or whatever it is comes off when I use my finger to get it off or a Q-tip soaked in alcohol and the other end to dry the area. I'd use my sink water, but there's so much crud in that it's not safe for motherboards, even the dishwasher isn't safe either since it only has 1 heat setting: hot.
