Lemon X-5 is a quaternary ammonium compound disinfectant cleaner, effective against a wide range of microorganisms including bacteria (both gram-positive and gram-negative), fungi and yeasts. And because Lemon X-5 is so efficient at killing these organisms which cause malodours, it is an effective deodoriser as well. Lemon X-5 also contains a vibrant, zesty lemon masking fragrance which provides a lingering perfume to aid in the deodorising of malodours.
