>>Assuming board cleaning is a good idea, just what does one use to remove that excess rosin? Bill K3UJ<<< I only use flux cleaner after a serious repair and only in the area of the repair as most flux removers do soften the solder mask. The best I've found is Chemtronics Flux-Off Rosin Remover (P/N ES835B). About US$7 with a built-in brush. -dave- N7DKK
