Marble Worktop - Cleaning

[jon_80]

I made (or I mean, agreed to) a bold move on worktops: a pale almost white marble top with a grey vein. It was part of doing the place up to sell.

It is a nightmare. We have been really careful, paranoid because of hearing about how these things react to things like vinegar and lime juice and avoided all that, but I have seen marks on it even from standing water. I am worried because there are these little spots where it doesn't shine any more and has gone matt. Much more of this and it could start looking not so new any more.

Are there any good cleaning products that can get the shine back on these dull spots?
