In days of Yore.. when I worked on stand-up arcade games, kids would 
spill drinks into the machine and the PC boards would get a nasty 
coating of black sugar syrup and dust... I would pull the board out of 
the machine and then take them to the industrial dish washing machine in 
the back. it used high temp steam and water jets... they came out 
looking factory fresh. I'd used compressed air to remove the excess 
water and then set them on a towel under a light to get them dry. Put 
them back in the machine and presto! All better. :)

Good advice! If you're having trouble with your annular ring, wipe it 
with something damp and make sure its clean. Especially if you had the 
flux. .. What?
