If urine has had time to soak into the concrete, we recommend cleaning the area with tri-sodium phosphate (TSP) to make it easier for OdorXit Eliminator to reach the urine. Using chemical resistant gloves, mix 1 part TSP into 32 parts water. Lightly scrub the mixture onto the surface. Reapply as needed to keep the area wet for 1-5 minutes. Using a shop vac, remove the excess liquid.
Rinse the area several times with clean water, using shop vac to remove any excess liquid each time. Do not let the area dry.
Use Ready-To-Use OdorXit Eliminator or prepare OdorXit Eliminator by mixing one ounce of concentrate with 32 ounces of water. If you are using a 16 oz. spray bottle, then you only need to add 1/2 oz. of concentrate and fill the bottle with water.
Saturate the area in Eliminator, either spray liberally or pour OdorXit Eliminator slowly onto the area, making sure it comes into contact with the entire affected area.
Allow the area to dry naturally.
