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.Â* I'd
usually start with a soak in Soda Crystals but that's a no-no for
aluminium.Â* It feels light and is non-magnetic.

Our gas hob (now replaced with an easy to wipe clean induction hob, as
my wife is disabled and has very weak wrists and finger joints) had
"chromed" aluminium burners and enamelled cast-iron caps. We didn't
bother about maintaining the finish and just shoved them in the
dishwasher - but it does strip the chroming.

The burner bits that you are describing are made of some sort of
aluminium based "pot metal" (mine are not chromed). I'd be surprised if
even concentrated washing soda attacked them at a significant rate (but
you could always try one and keep an eye on it for signs of reaction).
