Urine stains and odours, due to the uric acid crystals that urine deposits, can be very difficult to remove from a surface. Traditional cleaning products, such as soaps and strong chemicals, are ineffective at breaking down these crystals; thus, to remove deposits in a urinal, you need enzyme-based cleaners, specifically designed to bind to and break down the uric acid crystals while destroying the bacteria around uric acid crystals that causes odour. You can easily obtain these products online or in your home supply store.
