Engineered Specifically for Chains & Sprockets Degreasing Technology thats Safe for Motorcycles: DuPont Motorcycle Degreaser for Chains & Sprockets has been designed to melt away grease, dirt, wax & grime while leaving delicate O-rings unharmed. It has been independently tested to be safe for all sealed chains, including O-rings, X-rings and Z-rings. Many riders use untested chemicals, such as kerosene and other harsh chemicals that may accelerate the degradation of O-rings thereby compromising safety and / or causing riders to prematurely replace their chains. DuPont Motorcycle Degreaser will not adversely affect chrome or clear coated paint. Cleans with Your Safety and Environment in Mind: DuPont Motorcycle Degreaser was designed with safety, health and environment in mind. Virtually odor free, it contains only biodegradable ingredients which include soy-extracted esters. All ingredients meet the maximum Readily Biodegradable standard: Over 60% degradation in less than 28 days when exposed to the natural environment. Product is non-toxic to the environment when used as prescribed and contains no carcinogenic or hazardous air polluting (HAP) ingredients. Product exceeds federally mandated CFC, V.O.C. and California Air Resource Board (CARB) regulations. Cleans with Your Time & Convenience in Mind: Unlike other Eco-friendly degreasers that are water-based, DuPont Motorcycle Degreaser contains 100% active ingredients - no water! That means your chain gets cleaned more thoroughly, more quickly and with less effort. DuPont Degreaser aerosol features a strong ozone safe propellant that also helps remove grime from your chain and sprockets.
