Dross-B-Gone powder separates dross from molten solder. Applicable for wave soldering and other processes involving considerable volumes of solder. Is claimed to recover in several minutes almost 90% of the pure solder originally used. Is effective with both Pb-free and SnPb solders. Eliminates dross by quickly oxidizing it into an easily removable powder that is discarded, while pure molten solder remains in the pot and becomes reusable. Is sprinkled on the molten solder at an approx. ratio of 10 g per 1000 g of solder dross. The pure solder recovery rate is 880 g.
