Default Re: Redneck ( but effective) way to clean gas tank

I thought about the nuts, but was afraid I might not get them all out. So I used 10 pounds of BB steel shot, and 10 pounds of #6.
I was planning on turning it like you explained and doing it again. That's funny, I never heard of this being done before, thought of it all myself.
