Metal Brighteners

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.

Stainless Steel Polish/Cleaners

Clean and restore shine to stainless steel surfaces. These cleaners leave a finish that resists dirt, oil, and water spots.

Cleaners that are NSF registered C1 can be used in non-food-processing areas within food-processing facilities.

Cleaners that meet the EPA Safer Choice Standard are made of environmentally friendly ingredients. They also help you meet LEED Green Building standards.

Foam cleaners cling to vertical surfaces to clean them more effectively than liquid cleaners.

Cleaners that cannot be sold to Canada are restricted by product labeling requirements.

Simple Green Aluminum Cleaners

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.

Aluminum Polish/Cleaner/Protectants

Free of abrasives and corrosives commonly found in other metal polish, this polish won’t damage or degrade aluminum surfaces. Use it on bare or painted aluminum to clean, polish, and leave a protective coating in a single application. Often used in the aerospace industry on aircraft exteriors, it is also free of waxes and other ingredients that leave unsightly swirls and restrict repainting or refinishing.

Metal Polish/Cleaner/Protectants

Clean, polish, and protect aluminum, brass, copper, chrome, and stainless steel with this polish. It removes oxidation, tarnish, and surface rust without scratching or dulling brushed finishes.

Polish cannot be sold to the listed areas due to VOC (Volatile Organic Compound) regulations.

Stainless Steel Surface Restorers

These restorers remove weld scale, discoloration, black oxides, and other impurities from stainless steel (also known as pickling) while restoring the corrosion-resistant chromium layer.

Stainless Steel Cleaner/Protectants

Restore and maintain the surface layer on stainless steel that protects it from corrosion. Also known as passivating fluids, these protectants 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 protectants 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 protectants 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 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.

Liquid protectants are thinner than gel protectants, making them ideal for submerging parts. When spot cleaning, however, they will drip down 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 submerged.

Protectants for removing dirt and rust contain an additive that eliminates existing rust. Protectants for removing dirt only are less acidic and won’t discolor 400-series stainless steel. Do not use them on parts that have rust.

CLR Multipurpose Cleaner/Scale Removers

Jug

Pail

Drum

Clean rust and lime deposits such as calcium and scale from HVAC systems, coolers, tools, and vehicles. These removers are nonabrasive and noncorrosive, so they won’t damage surfaces. Derived from plants, they don’t contain toxic chemicals such as bleach, ammonia, alcohol, or phosphates. These removers break down quickly, so they won’t pollute air and water. They’re NSF registered for use in food- and beverage-processing facilities, and meet the EPA Safer Choice standard for environmentally friendly ingredients. They also help you meet LEED Green Building standards.

Chemicals

Also known as technical-grade chemicals, these industrial-grade chemicals are not suitable for food or medicinal use.

Nitric acid is used for industrial and laboratory applications such as treating wood, pickling and passivating stainless steel, cleaning electronic components, and etching metals. ACS-grade nitric acid meets quality standards set by the American Chemical Society. ACS-grade chemicals are also known as Reagent material.
