Help - need to really clean the metal potstandy things on my gas cooker

[PruniStuffing]

Have no idea what they're called.

You know the things - there are two or four of them, they're black metal, they go over the gas rings and grease sticks to them and gets burnt and I have never managed to clean them properly. Is there a miracle solution?

km that is a fine idea.
I'm going to do one bowl with washing powder and one with coke. Will let you know how it does.
