I ran across this in a magazine, It is some sort of environmentally safe snake oil. So I did a little searching and it seemed for real so I bought a gallon.

The stuff is really good - cleans grime of chrome with little effort, cleans plastic pretty well - it even cleaned all the grime out of my floor mats.
I am impressed and thought I would pass it on.
The price is pretty good based on performance and I will order a 5 gallon container.
