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?
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).
If its not plated, simple abrasion is a good way to simply remove the waste material and then slightly abrade 'what lies beneath' - finish off with fine wet and dry to restore surface sheen...
They feel like aluminium but I was surprised that was a material that would be used for flame. Just the one that has something burnt on it.
The usual method is to use XRF to identify the metal/alloy.....
I'd not expect it to be ally, more like stainless steel or chromed ferrous metal, try a magnet on them to see if its an alloy or not. Brian
AnthonyL explained :
The burner will not get that hot, there is a continuous flow of gas and air mix passing through it.
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.
you have to look for x-ray fluorescence spectrometer and the three main suppliers of this equipment are
Fischer scientific Niton Uk Oxford Instruments
They are not the sort of thing you will find on Ebay.
Alternatively you could buy a SEM with an EDS or WDS spectrometer attached but that means destructively cutting your object to give you a small sample to put into the vacuum chamber.
HTH,

Well, not for cheap anyway
Cody uses one in his mine, and Ben demonstrates one here
