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.

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

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

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

Citric Acid—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.
