I use salt, vinegar and warm water. The salt not only provided a safe abraisive but also acts to 'sterilize' the surfaces.

Extinct? Since when?
If it is a glass tank, you can also use a straight edged razor to get rid of the stubborn white spots.

I had a "mystery disease" tank, a 20H...every fishy slowly died in it.
Once all were gone, I left everything running and put 'one glug' of bleach in it (a few ounces?)...a week later the tank was VERY clean. I did a water change, added a bunch of dechlor. Re-cycled it with filter media from another tank. Fish are doing great in it now.
For the hard water stains, I'd get them wet and use a razor blade scraper to remove the worst. Vinegar or dilute muriatic (hydrochloric) acid may remove the rest; both are easily rinsed off vs something like "lime-away". you may find a permanent filmy stain in the glass...not much you can do with that.

Wow thanks everyone, I wasn't sure about using bleach on tank due to chemicals, I should of thought of vinegar though. thanks again everyone appreciate it. Now perhaps I can have pretty looking tanks to use.
Disinfection:
Remember that you are probably doing water treatments to get rid of Chlorine bleach already, so to some extent it isn't a problem. It is what I use. On the other hand, Peroxide breaks down into Oxygen and Water, so it would be safer. The thing is that Chlorine seems to be a better disinfectant.
I have also heard of using Potassium Permanganate, but don't know much about it.
Hard water stains:
You want some kind of acid, like vinegar or lemon juice or something like that. Do not mix this acid with Chlorine bleach though.
