Extreme Simple Green is the aircraft-approved cleaner trusted by aviation professionals. It cuts through heavy grease, oil, dirt, insect residue, and impact soils — fast — without harming aircraft metals, plastics, paints, or coatings.
Why It Works
A unique "triple play" formula combines two high-performance surfactants with a next-generation grease cutter. Together, they lift soils quickly, hold them in suspension, and rinse away cleanly — with zero redeposition. It even separates oil in oil/water separators.
