The grill that sits on top of my little barbeque is cast iron. The surfaces

A stainless steel grill I also have (but dont use much, because it does not
sit well on the barbeque) is easy to clean, because I can soak it in a water
tank for a week or two after use so the burnt will always scrape off easily.

If I soaked the cast iron one like that I think it would quickly turn to
rust. So would anyone have any experience of easily cleaning a rough
surfaced cast iron grill after use? Thanks.



Normally cast iron grills are porcelain coated (but not always).

Stainless steel grills are chromium coated.

Normally the simplest way to deal with both these types of grill is to seal
or prime them first.

Coat them in vegetable fat and then bake them in a 180-200 degree C oven for
a couple of hours, and leave them to cool in the oven. Do this a couple of
times. You will then have a natural baked on non-stick coating which you
should NEVER use detergent on, just wipe off the big bits of residue with a
damp cloth.

If this proves problematic, then "bake" the bits of residue with the barbecue
on full blast for a few minutes after which point they should brush/crumble
off easily.

The same principle applies to cast iron pans and skillets...
