Super Stain

I have become aware of the product, when I had my car for repairs in the workshop and the headliner had to be dismantled. The boys had probably not particularly paying attention and left all black fingerprints during installation. Very angry, I complained of this and the boss came personally with this cleaner and has the spots short hand away with a microfibre cloth. At first I was suspicious if that works, but any stains removed without discoloration or edges.
I myself have so easily a red smears (stripping a red painted object or lipstick, no idea as cars) and chocolate from light fabric.
