OOPS!  forgot:  After you are done soldering, if a "one-sided"  board, wash 
off the "rosin flux" with lacquer thinner and a toothbrush (let it  dry 
completely before re-use.  Else the taste is very bad!).
 
Then, spray the "bright" just-soldered/flux-free bottom with clear Krylon,  
etc.  
 
IF you have some conductor on the top, you have to be VERY careful using  
Q-tips or whatever to clean off the bits of flux here and there, among the  
components on top.  Be SURE and mask off all IC-sockets, screw-terminals,  
solder-posts, etc., and then spray the top, but be SURE not so much that it  "runs all 
in" the IC-sockets, etc!  Takes reasonable hand-care and maybe a  bit of 
experience!
