Remove oxidation, discoloration, and heat stains from most metals without causing pitting or other surface damage. Brighteners are often used to finish metal surfaces after welding and other fabrication processes. Dip, wipe, or spray on; then rinse off with water.

Also known as passivating fluids, these protectants remove dirt and discoloration from stainless steel, restoring or maintaining its corrosion resistance. They expose the chromium in the stainless steel, which reacts with air to form a protective layer. Use them on parts that are vulnerable to rust due to machining, heat, or chemicals. The citric acid in these protectants won’t create harmful fumes or hazardous waste, making them safer than protectants with nitric acid.

No need for mixing or monitoring pH levels, these protectants come ready-to-use. For sensitive parts, such as those made from 400-series stainless steel, you can dilute them with water.

All of these protectants meet SAE and ASTM international guidelines for passivating stainless steel. They also meet ASTM international guidelines for descaling and cleaning titanium and titanium alloys.

Protectants for removing dirt and rust contain an additive that eliminates rust that’s already on your part.

Liquid protectants are thinner than gel protectants, making them best for immersing parts. When spot cleaning, however, they can be hard to use on vertical surfaces.

Gel protectants are thicker than liquid protectants, so they cling to surfaces. Use them on vertical surfaces, weld joints, and other parts that can’t be immersed. Gels for removing dirt only have a higher pH value than all of the other protectants, which means they’re less acidic and won’t discolor 400-series stainless steel. Do not use them on parts that already have rust.

Less harsh than acid-based brighteners, these cleaners won’t damage or degrade aluminum surfaces. They are often used in the aerospace industry to clean aircraft exteriors and engine components. In addition to cleaning bare or painted aluminum, they are also safe for use on carbon fiber.

Quickly brighten and clean dull or dirty aluminum surfaces. These cleaners can either be brushed on or sprayed through a pressure washer. No scrubbing required. Good for any acid-resistant surface.

Designed for use in Fed. Spec. Class 100 and ISO Class 5 clean rooms, these cleaners won't leave a residue that could attract contaminants. They come sterilized and double bagged. They are also NSF registered A7 for use in food-processing environments as long as they do not contact food.
