Total horny stuff! I use it mainly for the wheels (car, motorcycle). This slightly oily wad everything is beautifully clean again. Also very nasty stains go away thus. For example, I went once on a freshly paved road. My wheels were full after all quite nasty, small black spots that wanted to go away no longer at. The manure seemed to have been burned literally. Have become almost insane. With NevrDull I then was fortunate enough to easily remove the stains. So I can only recommend highly enough!
