Just curious about cleaning the board after soldering is done. Normally, I'd just use 99% alcohol and a tooth brush. Then I'd let it dry and that's it. The board would be kind of sticky, but I ignored that. Recently, I built a GrubDAC and it was suggested to also run some hot water on the board to clean off the excess stickyness. The person said it was safe to do so. However, I've also read that you wouldn't want to do this with certain parts installed like a pot, or devices like a mosfet. What about the BJTs that are installed on the CTH, or Q1P, ICP, and ICH? Is it safe to put the whole board with all parts installed in an alcohol bath and then run the board under hot, soapy water to fully clean the board?
