Big white sink whatsit, how to clean?

[UnicornsPooGlitter]

I'm not sure what the sink is called - it's a large white double kitchen sink. I've been keeping it clean by using elbow grease and Method kitchen spray, but it probably needs something else. Any ideas what I should (and equally shouldn't) use?

If it's ceramic - Bar Keeper's Friend is the best thing ever. Then once it's clean a small scrub once a week with just a bowl-full of washing up liquidy-water is all that is needed.

If you mean a butler ceramic type sink the Flash Bleach spray is perfect. Keeps it sparkly white, no elbow grease required.

Yes, I think it's ceramic. Thanks.

Seconding the Barkeepers Friend. Our sink is quite scratched and that gets it really clean.

Biological washing powder. I discovered this years ago after washing smalls in the sink.

Thanks everyone, I used bio washing powder, and it looks a lot better.
