Using a portable sand blaster, connect a long wand to the nozzle. The extension 
allows you get the full  tank depth.  Once you have everything, it takes just a
few 
seconds to remove the rust. If you have oxidation on the sides you can attach a
tee 
to the wand or have the tank rolled.

For media you can use white play sand or pick up glass bead at a local
industrial 
supply house. The glass bead is extremely fine, several times finer than that
of the 
white play sand.

Upon removal of the rust, proper cleaning methods must be followed
