· How do I use Stink Free Urine Odor Remover? Stink Free Instantly Urine Odor Remover is a LEAVE-IN product. Just apply and allow it to air dry - DONE. Quick to apply, easy to use. Be sure to saturate an area wider than the surface stain. Urine is absorbed both horizontally and vertically, in a pyramid-like pattern which makes the contaminated area below the surface larger than the surface stain.

· What makes Stink Free Instantly Urine Odor Remover so effective? Stink Free Instantly Urine Odor Remover uses an aggressive, fast-acting OXIDATION formula that eliminates all urine odors, including those only pets can smell. It eliminates both the odor and its source by breaking down and changing chemical compounds into odorless, inert substances. It is NON-TOXIC, powerful and fast-acting.

· What is OXIDATION? This oxidation process is the same proven, odor-control process used by both government and industry (water treatment, waste water treatment, food processing and many other applications) where biological contamination and odor are serious problems. Stink Free backs up the oxidation process with an integrated system of odor neutralizers that track and destroy odor molecules for thorough and permanent odor removal. This oxidation process works, even where other processes, such as enzymes, fail. Oxidation works even on areas that have already been treated with enzymes. Enzyme odor removers are fragile, unstable, and take time to work. Enzymes deteriorate with age and when they are not maintained at moderate temperatures. Enzyme odor removers ONLY work within certain Ph ranges and will not work effectively when that pH range is disturbed, and often smell bad while they are working.

· How long does it take Stink Free's oxidation process to work? Stink Free Instantly Urine Odor Remover works instantly, removes urine odor completely when used as directed, smells good while it is working, and urine odor is permanently eliminated.

· Can I use Stink Free Instantly Urine Odor Remover even after I have tried other products that failed? Stink Free’s stable system of oxidation and odor remover are safe and work even after other products have been tried and failed. It works even after enzymes and other cleaning systems have been tried. It is not subject to slight variations in pH and temperature, and it is shelf-stable under normal conditions.

· Why do the instructions say NOT to use Stink Free Instantly Urine Odor Remover in a spray bottle applicator? Use Full Strength – DO NOT DILUTE. Your pet SHOOTS hot urine (over 100 degrees) down into your carpet or upholstery so that it quickly spreads out underneath the carpet or down into the upholstery. Urine is absorbed both horizontally and vertically, in a pyramid-like pattern which makes the contaminated area below the surface larger than the surface stain. Surface spraying will NOT sufficiently reach and neutralize the deep contamination. Stink Free Urine Odor Remover may be effectively used in a spray bottle for hard surfaces that are water-stable and color-fast.

· Which version should I use - for pets or cats - or do I need to buy both? Both versions of Stink Free Instantly Urine Odor Remover remove ALL KINDS urine odor thoroughly and completely when used as directed. Deodorizers dog urine, cat urine, small pet urine, and even removes HUMAN urine odor. It’s great for little kids just learning, geriatric care and other special needs.

· Can I use Stink Free Instantly Urine Odor Remover even after I have shampooed my carpet? Yes, it is safe and EFFECTIVE to use Stink Free Instantly Urine Odor Remover even after cleaning or shampooing your carpet or upholstery. You can also use it before shampooing, so that it can reach down into the under layers of the carpet or upholstery where urine odors hide. Be sure to allow Stink Free Instantly Urine Odor Remover time to do its work for greatest effectiveness before shampooing.
