Homebrew PCBs

I'm not sure what boards or process your using, but there may not be 
a need to coat the board if your using the positive resist boards. 

I haven't tried this, but Read at MG's site:
http://www.mgchemicals.com/techsupport/photo_inst.html

"Removal of resist is not necessary when soldering components to 
your board. By leaving the resist on, your circuit is protected from 
oxidation. Tin plating your board is not necessary. When soldering, 
the heat disintegrates the resist underneath the solder resulting in 
an excellent bond."

I am using the $3.99 6" x 3" boards by GC currently, but I will try 
next time to leave the resist on and solder through it. Then just 
using a flux cleaner to remove the solder flux, I suspect the final 
product might be very nice ;-)

Does anyone have a any home-brew flux remover formula?
I need to know what will clean a board of rosin flux easily/cheaply.
I am always looking for home-brewed concoctions as opposed to 
aerosol cans!
