Re: Brew for cleaning filthy gas tanks

[squierka39]

I tryed all kinds of earth friendly and not so friendly stuff in an aluminum tank with very old dry hard gas varnish. They didn’t work well, then I grabbed a can of oven cleaner spray, sprayed a lot of it in, let it sit about an hour, raised with hot water and some dish soap then lots of hot clear water. Came out nice and clean.
