EHC-UC™ is a specially formulated product designed for effective cleaning of toilets and urinals.
It contains powerful chelating agents, making it ideal for use in hard water conditions. It quickly penetrates and dissolves magnesium and calcium scales.
EHC-UC™ effectively removes rust and leaves cleaned surfaces smelling fresh and clean.
Safe for use on vitreous china, it will not cause any damage.
This highly concentrated formula ensures long-lasting use.
EHC-UC™ is available in quart bottles (12 per case) (Product# 25612).

In case of contact, wipe clean and flush with water. Prevent spillage onto skin, clothing, floors, lawns, or any other surfaces attacked by acid. Thoroughly rinse all accessory equipment with cold water after use. The dissolving action of EHC-UC may open up holes which had been lugged with rust and scale, particularly on old equipment. If this occurs, leakage should be immediately diluted with cold water and flushed away or mopped up while observing all necessary personal precautions. After the spent solution of EHC-UC has been discharged into drains or sewer lines, these lines should be flushed with plenty of cold water to further dilute the product.
Wear goggles or face shield and acid resistant gloves. Hold the product at arm’s length. Use only cold water when diluting this product. The sizzling action of this product may often be used as a guide to determine when the line is clear or when the solution is spent. This sizzling action occurs with carbonate deposits. It does not occur when deposits consist of sulfate, phosphate and other insoluble salts. Therefore, sizzling action may be used as a guide but when it does not occur, pH test papers should be used to determine active content of spent solutions.
Gas hot water heaters, heat exchangers, hot water coils and boilers, cooling towers, condensers:
These applications generally require larger doses than a quart. The user is referred to the detailed instructions on the larger containers of EHC-UC, or to the detailed instructions of the packet attached to this container.
Unit Heaters:
Fill coils with a solution of 2 parts cold water, 1-part EHC-UC. If a circulating pump is used, reduce strength of solution to 5 parts cold water and 1-part EHC-UC..
Boilers:
Depending on scale build-up, apply 10-15 parts of cold water to 1-part EHC-UC. After at least 12 hours, flush the boiler thoroughly. Before resuming operation, test with pH paper.
Toilet Bowls and Urinals:
Pour 1 pint of undiluted EHC-UC into Fixture drain. Cover drain opening to eliminate fumes. Allow to stand 15 minutes, then flush thoroughly.
Concrete And Plaster Obstructions:
Remove as much standing water as possible. Apply EHC-UC without diluting. When sizzling stops or solutions is spent. Flush thoroughly with cold water. Repeat treatment if necessary.
