This unassuming product is now a mainstay in my detailing arsenal. I had some filthy vinyl pieces in the unrestored '75 Jag -- years of neglect. As soon as I sprayed the product on, I could see it starting to loosen the dirt, scuff marks, and sticky grime. Wiped down with a barely-damp cloth, and the results were awesome. A big thumbs-up from me.
