The Flux Remover Pen provides a convenient method for touch-up cleaning of flux residues. This pen is a unique combination of hydrocarbon solvents and alcohols making it an excellent defluxer. Safe on plastics and rapid evaporating, the Flux Remover Pen dissolves type R, RMA, SA and most no-clean fluxes. Can also be used as an all-purpose cleaner for removal of light oils, silicones, waxes, greases and similar contaminants.
