If the tank is empty carry it outside and wash it well with Brillo,
that will clean it up. Rinse well, it will be fine.

Hmm, the tank is empty and has been for months. The soap will be ok? Won't the metal scratch the glass? My razorblade has scratched the glass before when I used to scrape GSP off.

Yes the soap will be okay, the brillo will scratch paint, not glass, get you a drinking glass
or wash a window using brillo see if it scratches it. Rinse well, it will be fine and will clean
the glass like new money.

I want to add to this simply for clarification>

When you do clean the glass with Brillo, it will clean it so well
that it will actually reveal to you just how many flaws and
scratches already exist on that said piece of glass....
Be warned
