A sanitation device commonly placed within restroom urinals, the subject of this article serves a dual purpose. It typically comprises a solid, often chemical-based, component that slowly dissolves over time, releasing cleaning and deodorizing agents into the urinal. This block is often paired with a plastic or metal grid-like structure that sits atop it, physically trapping debris such as cigarette butts and other foreign objects, preventing them from entering the drain system.
The implementation of these devices in public and private restrooms contributes significantly to maintaining hygiene and reducing unpleasant odors. Historically, simpler forms of urinal deodorizers existed, but the combination of the cleaning block with the physical barrier represents a significant advancement. This combination helps reduce drain clogs, minimizes the spread of bacteria, and provides a more pleasant user experience by controlling malodors.
