"Cling attacks and dissolves lime scale, hard water rust stains and urinary salts much better than watery bowl cleaners that just run off vertical surfaces. The longer cling time allows the active ingredients to be applied to the cleaning area longer. Pleasant cherry fragrance. Flush and remove water by plunging. Apply with swab until stains are removed. Rinse by flushing. Clean upper part of unit, also under flush rim at water outlets."
