Review (4/5): It Works!! Wish it came in larger containers!
I work in a cement plant and my truck has accumulated nasty build up. This stuff really works. Nothing special to do. It's as easy as the direction tell you.
The 1 quart spray bottle is not large enough to cover my pick up truck. As I said, I have too many years of accumulation for a single bottle. I will buy more just because I've waited way too long for plain vinegar to work.
