can you clean a fuel tank?

This is just pure genius..... I have used a jogger for paper (Printing Industry) and put BB's and Bleach in a tank and let it just vibrate away.... Spotless when finished. I have a cement mixer and am going to take a whack at it this way....

Thanks,
JW
I have a nice fuel tank from a 68 barracuda that I will sell you for 40.00 plus shipping
