Hey Gyver: I was just spoofin' ya about the deionized water (DI). Water of any type will probably make your solder connections go white. I posted your question to Dr. Lee on the latest OnBoard Forum. I suggest you check his responses. I short he

Hey Gyver: Oooow, using a pencil eraser has to take time. I would hate to be the person responding to your customer trying to explain the pencil eraser shreds accidentally left on the board. Awww, just spritz it with DI water and wipe it off with
