Like Larry, I solder all the holes with organic solder prior to the
last board wash.

I scrub my boards very thouroughly, but I do not rinse them with
distilled water. Our water, which has passed through a water
softener has never left a stain on a board. If I used unsoftened
hard water there probably would be a stain.

Some places have high iron contenet in the water which can leave
rust stains. I wonder if this could possibly degrade performance.
