Using your ASI Global Plastic Laminate Urinal Screen is a breeze. Just place it in the urinal according to its size. Make sure it fits snugly for the best performance. When it comes to cleaning, use a mild soap and water solution. Avoid using abrasive cleaners as they can damage the plastic laminate. Also, don't force it into a urinal that's too small, as this may cause it to break. For long - term use, check the edges regularly for any signs of wear and tear.
