>I haven't tried what you describe, but I did find that using >washable solder, and "not" washing it off, has a similar effect. 'Washable' flux is another way of saying 'you have to wash it off'. Rosin based flux does not have this problem. The 'washable' also leads to corrosion in time if not washed off.
