Heavy Duty Degreaser concentrate is not soy based. Heavy Duty Degreaser concentrate’s environmentally safer advanced cleaning agents work with the power of water to remove common oil, grease, and other organic deposits by breaking through the sticky bond they all share and once these bonds are broken by heavy duty degreaser water can then wash away the grime in an environment it normally couldn’t. What about rust!?! We thought of that! Heavy Duty Degreaser has built in rust inhibitors, so your parts are protected from flash corrosion by a thin invisible layer until they are rinsed clean. Our recommended dilution ratios are a great starting point, but you may find a better dilution ratio for your cleaning method depending on a variety of factors including the viscosity and density of the material being removed.
