The 1634-12S is a G3 No-Clean Flux Remover specifically formulated to remove stubborn, baked-on residues resulting from high-temperature, lead-free soldering processes. It is delivered as a powerful spray from a 12oz aerosol can, utilizing a strong solvent to blast away contaminants and clean hard-to-reach areas under components. This nonflammable cleaner evaporates rapidly, leaves zero residue, and is non-ozone depleting. Its proven effectiveness makes it ideal for post-solder cleaning on printed circuit boards to ensure assembly reliability.
