April 15, 200818 yr comment_1618 I just purchased a used 24 gallon plastic gas tank for my boat. In the corners of the bottom of the tank are some heavy varnish deposits from years of storing bad gas. I've tried to "pry" off the varnish (which has the consistency of tar/gum) but there is still quite a bit of it left. Remarkably, it is very tacky and does not want to come off. Will any of your products work to remove this varnish from a plastic tank?

April 15, 200818 yr comment_1619 Use a 1-1 solution of KBS Klean with very warm/hot water. Let the solution soak for 30-60 minutes. Repeat as necessary. You could also use the KBS Klean in your pressure washer. Please let us know if you have any additional questions.
