Malco Marine Deck Spray All Purpose Cleaner is a concentrated marine cleaner designed to tackle dirt, grease, oil, black streaks, bilge grime, and other stubborn soils on decks and hard surfaces.

Safe for use on a wide range of marine surfaces, Deck Spray works on both flat and textured non-skid areas and can be diluted based on the level of cleaning power needed. Its versatile concentrated formula makes it ideal for everything from routine deck maintenance to heavy-duty bilge and grease cleanup.

Deck Spray is also an excellent surface-prep cleaner when residual wax, grime, and contamination need to be removed before applying products such as Malco Marine HydroProtek Ceramic Spray Coating.
