    Image of Product. Front orientation. Rust Removers. Rust Removers, Gel Removers.
    Use gel rust removers on vertical surfaces to permanently remove rust. They’re stickier than liquid removers, so they won’t slide down walls or inclines before drying. Spray gel onto the rust, wipe off excess, and wait for it to dry.

    Restore and maintain the surface layer on stainless steel that protects it from corrosion. Also known as passivating fluids, these cleaners are made from citric acid, which removes iron from the surface of stainless steel that has been damaged from machining, heat, or chemicals. This exposes the chromium in stainless steel and reacts with air to form a protective layer. These cleaners also remove dirt, discoloration, and minor corrosion. Unlike nitric acid and other passivating fluids, citric acid does not create dangerous fumes and is safe for use throughout your plant. These cleaners come ready-to-use, so you don’t have to mix them, but you can dilute them with water for 400-series stainless steel and other sensitive parts.
    These cleaners meet SAE and ASTM international guidelines for passivating stainless steel. They also meet ASTM international guidelines for descaling and cleaning titanium and titanium alloys.
    Gels—Gel cleaners are thicker than liquid cleaners, so they cling to surfaces. Use them on vertical surfaces, weld joints, and other parts that can’t be submerged.
    For Removing Dirt—Cleaners for removing dirt only are less acidic and won’t discolor 400-series stainless steel. Do not use them on parts that have rust.
    For Removing Dirt and Rust—Cleaners for removing dirt and rust contain an additive that eliminates existing rust.
