I'll second (third?) everything that was said. Every time I've tried to skimp on washing after using a Kester flux pen I've regretted it. I use hot water, dish soap and a toothbrush, followed by compressed air to speed the drying. Where I used to work we had a can of some kind of solvent that worked faster and dried faster but I never bought any myself. -- Ben Jackson AD7GD <b...@ben.com> http://www.ben.com/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
