Borax is a white crystalline boron salt, ideal for rust removal and cleaning of metals such as iron, copper, brass, lead, and pewter.

• Dissolves metal oxides, providing a clean bonding surface
• Essential for soldering copper pipes
• Acts as a corrosion inhibitor, protecting sensitive areas of the bond
• Cleans and degreases the metal surface
• Ensures excellent and long-lasting adhesion of the bond

• Reinforces bonds with copper or phosphorus rods in copper pipes, brass pipes, and other ferrous metals
• Acts as a corrosion inhibitor against metal oxidation, ensuring long-term protection for the bond
• When dissolved in water at a 4% ratio, creates a degreasing solution for metal surfaces
