Zep Inc ZUCAL128 Calcium Lime Rust Remover 1 Gallon

Product Description

The ZEP INC ZUCAL128 is a concentrated calcium, lime, and rust stain remover formulated to dissolve hard water deposits, calcium scale, lime buildup, and rust stains from surfaces common in plumbing, HVAC, and pool service applications. Supplied in a 1-gallon container, this concentrate is designed for professional-grade cleaning tasks where standard cleaners fall short. Plumbers, HVAC technicians, and pool service pros rely on concentrated descalers like this one to restore flow, surface clarity, and system efficiency without mechanical abrasion.

This product is suited for residential and light commercial service work involving hard water scale removal on fixtures, pipes, heat exchanger surfaces, cooling tower components, and pool or spa equipment. It is particularly useful in regions with high mineral content in the water supply, where calcium and lime deposits accumulate rapidly. The concentrate format allows the user to dilute to the appropriate strength for the application, making a single gallon go further across multiple jobs.
