Hydrated Lime

Hydrated lime is often used to make building materials, such as mortars and cement, and to treat air and water.

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

Scale Removers for External Surfaces

Jug

Often used on the outside of cooling towers and condensers, these scale removers cling to vertical surfaces to dissolve scale and mineral deposits. Less harsh than other scale removers for external surfaces, they are safe for use on galvanized steel, stainless steel, and soft metals, such as aluminum and brass.

Toilet Bowl and Urinal Cleaners

Squeeze

Bottle

Eliminate stains and odors from toilets and urinals to keep your bathrooms fresh and clean.

Hydrochloric Acid (9% Concentration)—The most common cleaner, this acid removes tough stains, mineral buildups, and rust. Handle with care—it will damage metal fixtures.

Hydrochloric Acid (10-30% Concentration)—Our strongest cleaner, this acid works best against hard water deposits. Handle with care—it will damage metal fixtures.

Phosphoric Acid (20% Concentration)—Less corrosive than hydrochloric acid but nearly as effective. Use this acid on stainless steel and porcelain.

Citric Acid (3-7% Concentration)—The mildest and safest cleaner, this acid removes stains and mineral deposits. It may need to sit on tough stains longer or require repeated applications.

Nitric Acid

Also known as technical-grade chemicals, industrial-grade chemicals like nitric acid 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 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.
