Hi, Radio-Shack may still sell a flux remover. They are not as available as they used to be due to the Freon in them. Depending on the flux, Rubbing (Isopropl) alcohol sometimes works. I seem to recall that ethyl alcohol worked better, but it costs more and is not as easy to get. It might be cheaper to buy some 100 proof Vodka ( cheap stuff, not Stoly) , kind of a joke, but it is cheaper than the flux removers, and you can always use it if it doesn't work on the flux. .
