As a smoker and owner of three cats and a dog, I’m very pleased with your product. I’ve used it on furniture, carpets, mixed it with cleaner and cleaned the floors and misted it in the interior of my car. It’s so great to have a product that doesn’t stain or mark and doesn’t reek of some awful perfume. Thank you! I’ll be sure to recommend Nok Out to anyone with ‘smelly’ problems.
