Killing 99.9% of germs and viruses on hard and soft surfaces. Killing the source of mould allergens and controlling the growth of mould and mildew on hard surfaces. Eliminating odour causing bacteria to leave your home smelling fresh and clean. Dettol Glen 20 “gets to the source” of the odour without heavy perfume and eliminates damp musty odours in areas where air does not circulate. Ordinary non-germicidal sprays can’t do this.
