Calcium, Lime, and Rust 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.

Passivating Cleaners

Jug

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.

Liquids—Liquid cleaners are thinner than gel cleaners, making them ideal for submerging parts. When spot cleaning, however, they will drip down vertical surfaces.

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.

Harsh Chemical Neutralizing Granular Sorbents

Sop up hydrofluoric acid, solvent, and formaldehyde spills with these granular sorbents. They safely absorb and neutralize chemical spills in a single step.

Granules

For Solvents—Solvent sorbents lock in cleaners, thinners, and fuels such as toluene, mineral spirits, acetone, and methyl ethyl ketone (MEK). Unlike other sorbents, they capture harmful vapors and elevate the flash point of the spill to 140° F to reduce flammability.

For Formaldehyde—Formaldehyde sorbents soak up formaldehyde and other aldehyde solutions. They also suppress their hazardous vapors.

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 Reagent Grade—ACS-reagent-grade nitric acid meets quality standards set by the American Chemical Society. ACS-reagent-grade chemicals are also known as Reagent material.

Acid and Base Neutralizing Granular Sorbents

Neutralize and absorb corrosive liquids in a single step. These mineral-based sorbents spread over spills to quickly lock in and neutralize acids or bases.

Granules

For Acids—Use sorbents for acids on spills such as battery or hydrochloric acid. Not for use with hydrofluoric acid.

For Bases—Use sorbents for bases on spills such as sodium hydroxide or ammonia solutions.

Perlite—The sorbent made of perlite will change color when acid or base neutralization is complete.

Jar—The jar includes a shaker top to sprinkle granules over small spills.

Neutralization Tanks


Style A	Style B

Style C

For safe and legal disposal of corrosive chemicals, these tanks neutralize acid waste before it drains into sewer systems. Fill them with limestone chips (sold separately), which chemically react with waste to reduce its acidity. Often used in labs, these tanks rest on a solid surface below your sink. The inlet attaches to your sink drain where a P-trap would go, and the outlet threads into your drain pipe. These tanks are made of polyethylene to withstand prolonged contact with harsh chemicals.

Choosing a tank size involves several factors, including how much waste you generate and the types of chemicals you plan to treat. For effective neutralization, waste should spend three hours in your tank before exiting via gravity flow. Select a tank that is greater in size than the volume of chemicals you plan to dispose of in a three-hour period.

Styles A and B—Style A and B tanks have larger capacities to process greater amounts of waste.

Style C—Style C tanks have an adjustable-height inlet with a slip joint fitting to connect to sink drains.

Limestone Chips

Before use, fill your tank up to the outlet with limestone chips. One 50-lb. bag of chips will fill a five-gallon tank. Schedule regular maintenance to clean your tank and check the chip level—neutralization will erode chips over time. Disposing of non-chemical waste, such as coffee grounds, into these tanks will make the limestone chips less effective.

Electropolishers


Unheated Bath	Heated Bath

Dissolve microscopic surface flaws from metal parts for a mirror-like finish. These electropolishers send current through a conductive solution (sold separately) to remove a layer of surface material. They’re ideal for polishing intricate parts with hard-to-access features. Because they remove material evenly, they’re also good for applications where you need to polish your part without altering its dimensions. They’re small enough to fit on your workbench. Only use them on stainless steel and chrome workpieces.

Unheated Bath—A good basic option. These electropolishers remove material slower than those with a heated bath. They also distribute current less evenly through the solution, so they leave a less uniform finish.

Heated Bath—An upgrade in performance and finish compared to electropolishers with an unheated bath. These electropolishers use a heated solution that removes material faster and distributes current more evenly for a more uniform finish. They also output a higher wattage so you can polish workpieces with a larger surface area.
