#1 Rated Marine Degreaser by Powerboat Reports. A biodegradable, non-solvent heavy-duty degreaser that easily cuts through oil, grease and grime. Cleans and dissolves heavy soils on inboard & outboard motors, machinery and dock equipment. Also recommended for bilge cleaning. Marine Grez-Off® is VOC compliant, non-flammable and non-combustible.
Some surfaces such as aluminum alloys, plastic or painted surfaces are inherently sensitive to alkaline cleaners. Spot test on ALL surfaces before use. Do not use on motorcycles or glass. Use with adequate ventilation. Do not inhale mist. The use of safety glasses and rubber gloves is recommended. These directions must be followed or damage may result.
Before degreasing, be sure that all surfaces are cool to the touch. Do not apply in direct sunlight or if air temperature is above 100°F.
Spray MARINE GREZ-OFF full strength onto the cool, pretested surface to be degreased.
Allow MARINE GREZ-OFF to penetrate the soil. NEVER allow MARINE GREZ-OFF to dry on any surface. Stubborn soils may require brushing or a second application.
Immediately rinse with water until no sudsing is noticeable.
