I have an Electrolux rug shampooer and was trying to remove old odors of dog urine in my oriental carpets. I shampooed them then put a concentration of 4-1 water to Nok Out in the tank and went back over them. No more odor!! Worked great! Was sooo happy!

I heard about Nokout and Sniper when researching online for ways to get rid of the smell of cat urine. After reading reviews, I ended up ordering a bottle of Sniper and was cautiously optimistic. You see, we had adopted a feral kitten who decided my daughter was "his" and one day, out of nowhere, began marking and peeing all over her bed, dirty laundry, blankets, toys.. basically, anything that smelled like her I tried EVERYTHING I could to retrain him & clean everything but I thought we were going to have to get my daughter a new mattress, rip out the carpets and get rid of the cat to get rid of the smell. But, Sniper has been AMAZING. I was able to completely remove all urine and scent from the carpets, mattress, clothing and toys. It worked beautifully and left no smell, no fumes and didn't leave any discoloration. Because of all this, Sniper is now my cleaner of choice at home and I use it everywhere to clean and sanitize as well as freshen the air. I even use it in my daughter's gym shoes and soccer bag. Thank you so much. Seriously the best product on the market.

UPDATE. WE PURCHASED A NEW HOME WITH CARPETS THAT SMELLED OF DOGS. PADDING WAS TOO THICK TO TRY TO CLEAN. REPLACED FLOORS AND MADE SURE I USED SNIPER ON THE SUB FLOORS BEFORE INSTALLING NEW FLOORING. ALSO SPRAYED WALLS, ETC TO MAKE SURE MY CAT DIDN'T SMELL THE 3 DOGS THAT LIVED THERE BEFORE US. GOING ON 3 MONTHS AT NEW HOME. MY CAT HAS NOT HAD ANY LITTER BOX ISSUES LIKE SHE DID AT OUR PREVIOUS HOUSE WE WERE RENTING. SHE WAS SPAYED AT THE OLD PLACE BUT HAD BEEN VERY HORMONAL BEFOREHAND. STILL NO PROBLEMS WITH HER GOING BACK TO OLD BEHAVIOR. I CLEANED THE OLD PLACE WITH SNIPER WHILE SHE HAD SURGURY.SINCE OUR CAT CAN NO LONGER SMELL ANY OLD URINE SMELLS, SHE HAS NOTHING TO MAKE HER REOFFEND. WE EVEN GOT ALL OF OUR SECURITY DEPOSIT BACK FROM THE LANDLORD!! CAN YOU BELIEVE THAT!!?? I USED THE PRESSURIZED SPRAY BOTTLE WITH SNIPER TO COVER EVERY NOOK AND CRANNY OF THE TILE FLOORS AND USED SNIPER IN A HUMIDIFIER TOO! THANK YOU TED & SNIPER! JUST BUY THE BIG JUG! YOU CAN THANK ME LATER!
