These cherry-scented urinal deodorizer blocks work instantly to get rid of unpleasant odors. Made of paradichlorobenzene, the para deodorizer can last up to 30 days. They come in a box of 12, with each block weighing 4 oz and colored red.

Using these urinal deodorizer blocks is easy. Simply place one block in the urinal. For best results, replace the block every 30 days as the deodorizing effect may wear off after this time. Keep these blocks out of reach of children and pets as they contain paradichlorobenzene. Store them in a cool, dry place. If you notice any signs of damage or reduced fragrance, it's time to replace the block.
