Homebrew PCBs

Thanks for those who replied. I am using the toner transfer method, 
so i guess my best bet is some tinnit. What i do to clean of the 
liquid flux is by using a toothbrush with rubbing alcohol to remove 
the excess. I have a few more questions, One, what is the best 
technique to solder an ic socket on double sided pcbs? And secondly, 
In Eagle Cad, how does one increase the width of the tracks when you 
autoroute a board? Thanks, Genaro
