Krud Kutter The Must for Rust FAQs



  • 1.

    What is rust or oxidation?

    Metal rusts when surface molecules combine with oxygen, creating an oxide. It is a simple chemical reaction requiring only metal and air. 

  • 2.

    Why does rust contain air?

    Rust contains air because it is porous. This oxygen in rust is enough to continue the rusting process even after the surface is coated with paint, primer, plating, etc. This leads to coating failure. No matter how carefully the metal is fabricated, machined or packaged, rust can always form.

    What is The Must for Rust specifically intended for?

    The Must for Rust is designed to dissolve rust and oxides from metal surfaces, protect metal surfaces for up to 12 months and prepare metal surfaces for painting, priming or coating.

  • 4.

    What will The Must for Rust remove?

    The Must for Rust quickly dissolves rust from iron, steel, aluminum, chrome, galvanized surfaces and auto cooling systems and removes blueing from firearms. It also dissolves most calcium, lime and other hard water stains on porcelain, tile, fiberglass and glass.

    How does The Must for Rust remove rust?

    Since The Must for Rust is a low-viscosity liquid it penetrates into every void of a metal surface and dissolves the oxidation through chemical actions. Then tiny elements (sometimes seen as white crystals) are formed and become integral with the surface molecules of the metal to resist rusting again. The corrosive agents attack these crystals instead of the metal. The crystals become part of the metal surface. There is no "build" as with a paint film and it does not react with any solvent or vehicle that is found in paints, coatings, etc. No gassing occurs with heating.
