Caution: Super Clean will damage paint if left on to long.
I second this: (Including the paint damage. Also, decal and finger damage.) I use Zep Morado; but it seems to be about the same thing as Super Clean. I cleaned a really nasty JW tank with it, in relatively no time, where lacquer thinner barely would touch it. Also, the thing with lacquer thinner is that it seems to work well breifly and then go dead. You have to keep changing it and it's kind of expensive. Then, what do you do, morally, with all the waste? I am absolutely sold on Morado/Super Clean.
