Homebrew PCBs

Hi,

Thanks for all that info.  Apparently the 98% IPA is just moving the 
flux around, but the board appeared significantly cleaner than when I 
used rubbing alcohol.

Do you know of any less labor intensive cleaning?  I'd like to be able 
to clean the boards at my workbench and not have multiple cleaning 
steps.  Though I will try washing a board with detergent after 
cleaning with anhydrous IPA.

I'm trying to use the least dangerous chemicals as possible.  I use 
acetone, but sparingly.

Regards,
Dennis
