What is the procedure for removing Flux residue?
Stay-Silv Flux can usually be removed by washing or immersing the part in water immediately after brazing. Brushing in conjunction with water quench may help remove stubborn residue. If water isn’t sufficient, use a stainless steel brush, jets of steam, emory cloth or blast cleaning. Chemical removal may be necessary. A mild acid solution of 10 – 25% by volume hydrochloric or phosphoric acid is often effective. Heat solution to 120 – 150F. Neutralize in solution of soda ash and water, followed by a clear water rinse.
