When all else fails use Urine-Erase. Designed to remove tough, set-in, urine stains and odours, Urine-Erase utilizes a two-step process. Unlike other enzyme based cleaners Urine-Erase does not add the enzymes at time of production. Instead, the enzyme powder is mixed at home just before using the cleaner. This ensures full potency and best cleaning performance. The enzymes work to break down the biological material in the urine to completely remove the odours. After the enzyme solution has sat on the area for 8 hours the second step, which is a Hydrogen Peroxide mixture, is applied to the stain and left to dry. After both steps are complete the surface will be free of urine odours or stains.
It is important to note: for best results apply the same volume of Urine-Erase as urine deposited in the affected area.
