cleaned apt carpet on monday . dark brown very dirty. used CMS citra brite in bucket brush went back and forth up and down let set . used rx20 to clean and wand. There was some urine issue used OSR on them let set for 30 minutes used water claw raked put air movers . went back wed and still smelled carpet was very clean looked good. I then used X-cide from CTI sprayed on raked in . That was in the morning came back at five and still smelled. I have used judson 02 with good results on these carpets before but at almost 50 dollars a gallon its a little expensive and i would have to order some since I do not have any. any other suggestions would help. Thanks Steve
