The BrushClean system cleans three ways with one convenient package: spot clean economically with the brush; flush under SMDs with the extension tube; and clean large areas with the spray nozzle. The brush economically applies solvent only where you need it. Solvent flow flushes brush clean. A new brush is supplied with every easy-grip can. BrushClean Flux-Off products are specially formulated to remove all types of rosin (types R, RA and RMA), no-clean and synthetic (type SA) flux. Quickly removes all rosin-based flux residues; excellent material compatibility; penetrates tight tolerance areas; low odor and leaves no residue; also removes oil, grease, and ionic residues. Eliminates flux residues and cleans: through-hole circuit boards, surface mount pads, chip carriers, ball grid arrays, switches, SMT components, metal or plastic housings. Shelf life is 5 years. Sold in a 5 ounce aerosol can with attachable brush included.
