Urine, whether cat urine, dog urine or other urine including human urine, consists of urea, urochrome and uric acid crystals. Most general cleaners only remove the water-soluble components of urine (urea and urochrome) but leave behind the non-soluble uric acid crystals that retain the urine stain and strong urine odour. These crystals attach to surfaces and are very difficult to dislodge. Any humidity or dampness will trigger the dormant crystals bringing back the urine smell. urineFREE’s bio-enzymatic formula eats up the urine and uric acid crystals whilst removing the urea and urochrome components, eliminating both the urine stain AND the urine odour for good. urineFREE contains no harsh or hazardous ingredients, is biodegradable and environmentally friendly and is safe to use around humans and animals.
