I have cast iron supports on my cooker, they are a pain to clean. I was told only to wash with soapy water and nothing else as it's cast iron. Some parts of it has silver marks, I don't know what that is, I tried scrubbing it. Is the coating that's come off it? It's really annoying as it's a new cooker that I've only had for a few months, and clean after every use.
I've attached photos, on one of the pic you can see it looks rather orange, is that rust? Because it's so hard to clean off!
I know cast iron can rust if water is left on it, is that the case here, am always drying when there's water fall out from pans as am worried about it rusting
