I would like advice on maintenance tips ?

I would like advice on maintenance tips or products
needed to restore Botticino (Marble Classico, Classico
Extra or Fiorito) one of these we think. The foyer has
some minor scratches and has never been polished at
all in 12 years. It still looks good. It looks like
there is a layer of water on it. The same marble is in
a shower and is in poor condition. It must have been
cleaned with abrasive chemicals by the previous
residents. Can it too be restored and sealed so that
it is protected and looks beautiful. It looks good
when there is water on it.

Thanks,
Thomas McDonald.
