Don't use that whimpy phosphoric acid ;) Use Muriatic acid. Just be
careful not to leave it in too long, or ya may have a tank made of paint
only! Farm supply places sell "milk stone remover". This acid is supposed
to leave a layer of zinc that protects from rust. I thought that it was
phosphoric acid, but I guess it isn't.
Acetone will work as good as MEK. Use whichever is cheaper.
Definitely coat the tank with a sealer afterwards!

Milk stone remover, is fine. You won't notice any rusting if you dry it
soon. With muriatic, it will noticabley start rusting when you rinse,
plus it is much more toxic and foul...
