Rufluid Soldering Flux FLSRUBYFLUIDSS Editorial Review
The RubyFluid Stainless Steel flux is a highly effective product for soldering stainless steel, stainless to stainless, stainless to copper, copper to copper, and copper to carbon steel. It is compatible with tin/silver and silver bearing plumbing solder. However, it is not clear if it is compatible with lead-free (tin copper selenium) wire. It works excellently with 18-8 stainless steel and brass. Customers found RubyFluid Stainless Steel flux helpful in soldering stainless steel BBQ skewers, custom throttle cables, and stained glass copper foil. They noted that only a little was needed, and one pint bottle could last a lifetime. While some complained about the lack of directions or best practices guide, most customers found the product highly effective and easy to use. They recommended washing this flux off after use as it is corrosive and there is a need for good ventilation while using it as it creates a very acrid smell.
