Stay-Clean® Liquid Flux
A General Purpose Zinc Chloride Flux For Soldering with All Soft Solders Use with Tin-Lead Solder, Tin-Antimony Solder, Stay-Brite Solder.
Stay Clean liquid effectively removes surface oxide and prevents oxide formation during soldering. Stay Clean can be used with most tin based solder compositions and is an excellent companion flux with Harris Stay Brite® and Stay Brite® #8. Stay Clean is an active soldering flux. It works well on copper and brass but is more frequently used on base metals that require a more aggressive flux, such as steel, nickel, and stainless steel, (it is not suitable for aluminum or magnesium).
Minimal pre-cleaning is required with Stay Clean Flux, but it is good practice to remove excess oil, grease, or other surface contaminants prior to fluxing and soldering.
Flux should be applied with a brush or other type applicator. Avoid getting excess flux inside tube or other connections..
Flux residue is corrosive and a post-solder flux removal procedure should be employed. Because of this it is not recommended for use in electrical or electronic applications.
