CLR Brands is dedicated to setting the standard in solving hard water and rust problems. Building upon the trusted performance of The Original Calcium, Lime & Rust Cleaner, we've enhanced its efficacy by introducing a renewable, cellulose-based thickening agent. This advanced dirt, grime and hard water stain remover adheres to vertical and hard-to-reach surfaces, minimizing drips and maximizing dwell time for targeted, high-performance cleaning. The thickener’s natural wood-fiber composition provides mild abrasiveness for improved soil removal without damaging surfaces. The result is faster, deeper penetration of calcium, lime, and rust deposits—ideal for spot treatment and large-area applications alike. CLR Brands Original CLR with CLING is certified by the EPA's Safer Choice Program as a safer alternative to traditional chemicals. It is bleach-free, phosphate-free, and ammonia-free. Effective, safer, and engineered for precision—this is the next generation of rust and scale removal.
