As per subject, what material are the gas burners on the hob made of?

SWMBO has burnt something onto one and wants me to clean it off. I'd
usually start with a soak in Soda Crystals but that's a no-no for
aluminium. It feels light and is non-magnetic.

It's a Russell Hobbs and the only help in the manual is to use a metal
surface cleaner - suggestions?


The usual method is to use XRF to identify the metal/alloy.....

Can't find a decent spectrometer on ebay

Several Niton XL2s, but none under £10k. I've used much earlier
versions, IIRC they were about £5k in the 1970s.
