This ready-to-use Waterless Urinal Cleaner uses odor encapsulation technology to control odors. Waterless urinals should be cleaned multiple times daily, depending on usage, and serviced periodically to operate effectively and reduce smells. The daily cleaning process is simple and will only take a minute or two per urinal. Apply once a day, unless the urinals are in a high-use environment, such as a convention center, casino, or airport. High-use urinals may require additional treatments daily.
