I've only had the new Franke sink a few months and now it's starting to get
a light tan hue from tea stains.
So far I've bought Inox Creme ('the best care for every stainless steel sink
from Franke') but it is a gentle cream and just gives a brilliant shine
without removing stains. "Shiny Sinks" was sold to me by the local diy shop
but on my return home I decided it was too harsh and would not do. Now I'm
stuck as to what to use. Any ideas?
Bleach, or a cleaner containing bleach such as Flash Kitchen Spray. We
use the latter to remove the tea stains from the worktop, sink, and even
the inside of cups.
Of course it doesn't actually *remove* the stains, it just renders
them invisible (though if you're being pedantic I suppose a stain is
only a stain if it's visible). I discoverd this when I used bleach on
some photographic developer stains many years ago, they disappeared
beautifully but the moment some more developer hit them they became
instantly brown again.
That is not *necessarily* so. Bleach and caustic soda work by chemical
recations. They change the chemical composition of what they bleach. If
teh end product is water souluble, it will simply wash away.
Viz a grease stain will end up as soap and be gone for ever.
The tendency of caustic is to rip other molecules apart, leaving
fragmenst with various groupings on them left over. Its very rarely a
reversible reaction. Well not without considerable equipment and
knowledge anyway 
Anyway I use caustic on things like stained china and steel sinks, and
mainly, it's fine. I have ended up staing some things - can't recall
what - but mostly its pristine woderfulness afterwards. Beware of its
effects on plastc tho - can make tghe waste pipes brittle, so not to be
used too often.
Personally I think life's too short to want stainless steel to stay
pristine on the bottom of the sink.
