My white sink is turning me into a compulsive cleaner!!

[Notcontent]

I have a white corian worktop and sink. It looks great and the worktop is pretty easy to keep clean. But for some reason the sink seems to stain quite easily and I am scrubbing it every evening. In my old shabby kitchen I had a basic metal sink and whine it was not pretty, I never worried about it… Am I doing something wrong? In the first few weeks of having the new sink I was not careful and left some used teabags in it, which was a bad mistake….

Is it just me or are those types of sinks high maintenance?

I have a beautiful cream composite sink. It's so hard to keep clean! If the frying pan gets put in, it rubs dark marks on the side
I still can't actually get them off.

My DSis had a black sink and worktop which she hated because it showed every water stain. I have white quartz top which is brilliant and doesn't show a mark and a white Belfast sink. I just run bleach around the top edge of the sink once a fortnight and leave it for an hour and rinse. It's 5 years old and looks brand new. Just ordinary supermarket cheap bleach. No yellowing
