Beaphar odour eliminator uses friendly microorganisms as its active ingredient. As soon as Beaphar odour eliminator comes into contact with unpleasant odours the microorganisms are activated and set to work, eating it away. With stubborn lingering odours, place a damp cloth over the spot. The microorganisms will remain active for weeks. Spray liberally onto stains. Let the product act for several minutes. Remove dirt with cloth or sponge and rub firmly with a slightly moist cloth. Stubborn or aged stains may require a second application. Wash the hands after applying the product.
