Neff Oven Enamel Corrosion

I would suggest it is not Enamel as I understand it.

Enamel is damaged by either acids or alkalis (depending how it was formulated). Kitchen enamels are usually designed to be resistant to acids and therefore dissolved by alkalis. Oven cleaners and dishwasher detergents are alkalis - does it come in to contact with any of these?

Bath enamels on the other hand are resistant to alkalis so they're not damaged by soap, but this means they are damaged by acids.

If it has any sharp bends in it or friction applied to it it can craze, and if its something that can rust or oxidise, it will. I got rid of a perfectly serviceable Philips Microwave that had a drop down door due to similar problems just inside the front bottom edge of the cooking cavity. Strangely nowhere else flaked or rusted, as it was mostly stainless or an alloy. This piece needed to be strong as the hinges were mounted on it.

I guess the first question is, what the cause actually is. Brian

Talking of Baths, yes my bath has lost its shine and I had thought it was our hard water. Its quite old now and is metal, but its annoying as non slip mats no longer grip and I imagine its only a matter of time till the white will wear away. Problem is with today's cleaning products, they change the formulation and do not actually make it plain and so what was safe one week might not be in another bottle. You cannot win. If only baths were plug and go. I mean you can bet that any new bath will be a different dimension to the old one meaning tiling changes and lots of filler etc and different pipe work.. Brian

Ok, mea culpa, I used the same terminology as the 'engineers' who came to inspect it but am happy to accept it's probably not enamel in the commonly understood meaning.

It is the coating on the inside cavity of the oven, whatever it actually is :)

No, it's just had a wipe out with a damp non-abrasive cloth, the instructions say not to use oven-cleaner on the coating so I haven't.
