We bought a new Siemens hob with a front wok burner in October. Didn't own a wok, so bought one at Xmas and first time I used the hob (which was spotless) with the new wok, the actual steel/aluminium burner looked like a bunch of students had been at it and not cleaned it for about a year. Looked like brown grime everywhere.
Scrubbed it for ages with wire wool (steel wool scourer too big to get into the grooves) and soaked in vinegar solution, used ancient electric toothbrush etc and it looked better but still old and grot.
Siemens sent an engineer who said "it's normal to discolour with time" (first time?!) and he'd organise a new one as a gesture of goodwill. I'm still waiting.
Used the burner for the 2nd time today for lunch and guess what - the brown grime spotty look is straight back. Currently is soaking in vinegar again

I wish I'd not bought a hob with a wok burner as always managed stir fries with a normal burner with my old gas hob, but is this normal for these burners, or is my one a particularly feeble metal or something?
I'm neurotic about the new hob and it gets well cleaned daily. The burner covers discolour easily too. Wish I'd not changed my old one as cranky though it was, it was better quality.
This new one was £300 too
