[jamboree]

anybody know where to buy rubbing alcohol for cleaning PCBs?

Your typical Guardian/Watson will have it. You won't get 100% pure (unless you got lobang in pharmaceutical industry), normally they have 80% concentration, but that's good enough. Just make sure your board is thoroughly dried before powering on.

Yes, Guardian bro. You can find it there!

I use either lighter fluid, paint thinner or turpentine.

No problems to date.

+1 to this. Double up as first aid kit necessities

Yup, I used alcohol wipes (those small square type) to clean off old thermal paste off the CPU and cooler previously, no issues at all. Try not to use them on non-flat surfaces as the fibers will get caught in the pins and edges.

Agreed. It's my daily must-carry. Useful for cleaning permanent marks, toilet bowls, fingerprint stains etc.
