Flux removers (defluxers) remove flux residues and other contaminants left by manufacture, rework, or repair of printed circuit boards. Residues from higher, lead­free temperatures are more baked on and harder to clean. G3, Ecoline and Precision­V flux removers have been proven very effective at removing fluxes baked on at lead­free temperatures.

Micro­components and fine pitch leads are delicate and easily damaged, so brushing and scrubbing should be avoided if possible. Both G3, Ecoline and Precision­V have a powerful spray and strong solvent that blasts off residues and cleans areas under components that a brush cannot touch.
