We bought a (bloody expensive) BBQ this summer. We´ve bought a cover for it but there are rusty bits all over it. Hubby and I disagree as to what we should do. Can someone give some advice?

Thats easy, take it back to the shop where you bought it.

Thanks for that!! Not!!
I was thinking more along the lines of do we oil it before we store it or would that just attract dust? Is a good seeing to with a wire brush in order?

I would wire brush it then give it a light coating with vegetable oil, I always used to treat my non stainless wok like that, and it always stopped rusting, and was always OK even when not used for several months.

Will try that, thanks for the advice
