The Uric Acid in urine is the real cause behind those nasty smells left behind by your cat. The uric acid is responsible for the formation of crystals which are left behind when a spill is cleaned up.
These crystals then become reactivated when they come into contact with moisture and they strong urine smell then returns. Also your catsacute sense of smell also picks up on these crystals and then feels the need to remark their territory and the problems then reoccurs - another stain!
Most stain removal products on the market contain detergents and masking agents which simply lock in the smell around these crystals, but do not remove these source of the prodblem - the crystals.
Urine Off contains bacteria and enzymes which effectively eat or absorb the crystals, as well as the other components which make up urine.
Removing the crystals is the key to this great product!
