I have found the best option is to use a enzyme cleaner. I highly recommend BIOZYME found on www.cleaners-r-us.com. I have tried many other expensive $$$$ enzyme cleaners and none of them work as well as BIOZYME. You just saturate the surface and it will completely remove the urine from the fabric. You can also use BIOZYME on carpets, mattresses, etc. Currently Cleaners-r-us.com is offering 10% off your purchase of Biozyme using coupon code: CM81 during checkout. Hope this helps!!
