Factory Gas Tank (1 Viewer)

[Waterboy]

I just recently purchased a factory gas tank for my FJ. There is no rust at all on the tank. There is a little bit of sludge in the bottom. Whats the best solution to cleaning the inside of the tank?

Thanks,
Preston

for the price of solvents to wash it out, id just run It down to a Radiator shop and have It boiled out.
