Homebrew PCBs

That's a good one! I can't find mentioned product here, so i tried 
similar stuff - tarnish remover - i found Cillit Bang in local 
store, tried on some old copper and it cleaned it perfectly! I will 
try transferring tomorrow to see how it works in real life, but for 
now thanks for info!
