Urinal balls and urinal screens are two types of products used to maintain cleanliness and freshness in public restrooms with urinals.

Urinal balls, also known as urinal deodorizer blocks, are small blocks of deodorizing material that are placed in the bottom of the urinal. They are designed to slowly dissolve over time and release a fresh scent into the air, masking unpleasant odors that can accumulate in the urinal over time. Urinal balls may also contain enzymes that help break down and remove uric acid buildup in the urinal, helping to prevent blockages.

Urinal screens, on the other hand, are typically made of a flexible plastic material and are placed over the drain of the urinal. They are designed to catch debris such as cigarette butts and other litter that can accumulate in the urinal and cause blockages. Urinal screens can also contain deodorizing agents to help keep the air in the restroom fresh and clean.

Both urinal balls and urinal screens are commonly used in public restrooms, and they can be found in a variety of scents and colors to match the decor of the restroom. They are typically inexpensive and can be easily replaced as needed to maintain a clean and fresh-smelling restroom.
