Depends on how bad it is. I usually just pressure wash the inside with soap then rinse. I then empty out as much of the water as I can, blow it out with the long nozzle on my air hose, pour a couple of bottles of HEAT in it and slosh it around to absorb what moisture is left, and let it dry out good. That works on most of them.....

Be sure and put a new fuel sock on the end of the pick up tube.

There was a post on here a few years ago where a member put some gravel or old nuts and bolts and a little sand in his and bungee strapped or ratchet strapped it to his tractor tire for a few days. He said that thing was so clean inside that you could eat off of it....
