Bowden's Own Orange Agent Degreaser is a safe and powerful engine cleaner. Not only is it environmentally friendly, but it uses an effective, non-corrosive, water based citrus formula so it will not damage delicate parts of the engine and ancillaries. The formula rapidly dissolves oil, grease and grime and penetrates built-up stubborn residue with minimum fuss. It's safe on paint, metal, alloy, chrome and most plastics. Orange Agent gives a showroom clean finish with no white residue which means you won't be afraid to lift the bonnet in the presence of others and show off on the next car club run. A cleaner engine makes it easier to spot leaks, which means you can see any new things before they become a problem. Plus, clean engines run cooler. An engine caked in crud will always tend to run warm, so, do yourself and your car a favour, clean it all down before the next summer road trip.
