Re: Restoring corroded hob plates
 

Aha ... now, grinding paste and oilstone is something the Aga DIY website I found was talking about. Do you know any more about that, such as where I would get the kit? Is it something I might find in B&Q?

When I said a millimetre, by the way, what I really meant was 'just a little bit' ... I wasn't planning to scientifically remove a mm of the surface. I know it'd take forever ... :disturbd:

Grinding paste you can get from an autoparts shop (valve grinding paste, usually you get course and fine grades in two halfs of a tin). The tins tend to be small so you might need a couple at least.
The oilstone I'm not sure. I would think somewhere like Machine Mart (they may have grinding paste there too, in larger tins). You don't want one that's too small because the idea is to grind the hob plate flat (for best thermal contact with your pan of curry! ;) assuming of course you are using those flat thick bottomed pans which you're supposed to on a flat hob plate).
Oh, and you grind in a figure of 8 pattern rather than back'n'forth or circular.
EDIT: Those common little oilstones about 1" x 3" are pretty useless for this job. You probably want something the size of a beermat.

Oil-based whetstones are so old hat these days. You could try a diamond based one from DMT or similar - they just need a little water as lubricant. The extra coarse (black) ones don't half shift some metal.

I too mentioned that earlier. Saves a lot of arm work.
