1 x 1 liter refill bottle EcoPet Odor and Stain Remover is a bio-spray that effectively removes unpleasant odors and stubborn stains from sources such as cat urine, feces, vomit, blood, wine, and coffee. It can be used on textiles, carpets, furniture, pet beds, cages, and litter boxes. Unlike ordinary air fresheners, it neutralizes the odor instead of masking it with perfume. For cat urine on hard surfaces like concrete, stone, and grout, UF2000 is recommended instead.
