Does urineFREE work on old stains as well as new stains?
Yes old urine stains can be removed using urineFREE.
However old urine stains usually take more than one application as they may have penetrated deeper into the surface of which you are treating. For example old urine on carpets may have penetrated the underlay and sub-floor. urineFREE must make contact with all urine to be 100% effective and this may require several applications, time and enough product.
Often the old stain will become darker and the smell stronger on the first application. This is common as the urine bleeds to the surface. Subsequent applications will get it all.
