I found that because it doesn't leave behind any oily residue or films, it is actually a superior choice for prepping metal surfaces for paint. You can dilute it anywhere from four to ten parts water to one part cleaner, making that single quart go much further than a standard petroleum-based bottle. It tackled everything from engine grease to soap films on vinyl without the flammability risks. Just remember to rinse the area thoroughly with water afterward, and if you are working on bare metal, follow up with a metal prep to ensure that professional-grade adhesion.
