Features and Benefits:

A biodegradable, water-based cleaner that effectively removes heavy duty grease, dirt, fifth wheel grease, lubricants, oil, hydraulic fluid, grime, heavy molly grease, tar and more! Nonflammable, no fumes, no abrasives, no acids. USDA approved and VOC compliant in all 50 states.

Some surfaces such as aluminium 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 protective 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 GREZ-OFF full strength onto the cool, pretested surface to be degreased.
  • Allow GREZ-OFF to penetrate the soil. NEVER allow 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.
