Kester 5779 Bio-Kleen formulation is a highly concentrated liquid cleaner which is added to water to form a non-foaming solution for removing rosin flux residue. 5779 is 50-100% more concentrated than most other aqueous flux removers. This results in substantial savings in the amount of cleaner consumed. The use of this product permits solering of electronics assemblies with non-corrosive rosin fluxes and eliminates the use of more expensive chlorinated and fluorinated solvents that are more toxic and pollute the environment.
