A biodegradable, general purpose cleaner for use where a neutral cleaner isn’t strong enough. Contains a proprietary blend of high performance detergents and chelating agents that quickly penetrate and emulsify soils – even grease & dirt. Ideal for use in scrub and recoat systems prior to top-coating with new finish. Concerto is strong enough to remove any soils that may have been burnished deep into the floor finish; yet will not remove the good finish under it!
