I want to get our old laminate kitchen worktops changed for new ones. I've been looking at granite and quartz worktops which look lovely. How difficult are they to clean though? I don't mind them looking a bit dull where water hasn't been cleaned up, but don't want them stained with tea/pasta sauce etc. There are lots of posts about cleaning granite worktops, but it isn't always clear if the problems have been that they are a bit dull (which I can cope with) or are actually stained.
