Hi folks, Does anyone know of a way to remove rosin flux and clear lacquer (Electrolube CPL) from an uncoated PCB? I've been using a toothbrush and isopropyl, but that doesn't seem to be particularly effective - it takes a lot of scrubbing to get the flux off and tends to leave a sticky flux residue on the board. Does anyone know of anything that will remove flux, but not leave the sticky residue? Thanks. -- Phil. | Acorn RiscPC600 SA220 64MB+6GB 100baseT philpem@philpem.me.uk | Athlon64 3200+ A8VDeluxe R2 512MB+100GB http://www.philpem.me.uk/ | Panasonic CF-25 Mk.2 Toughbook ...
