t Efficient way to clean dirty Bronze burners from a gas cooktop

Attachment 480388

What are efficient and fast ways people have used to clean these? So any methods using chemicals and machines I am interested in.

Currently we soak them in vinegar for hours and then finally use steel wool on them.

I had taken to using 400 grade wet and dry sandpaper on the top round surface of the burner as well.

I have a bench grinder with a grinding stone and wire wheel, I assume the wire wheel would be too strong. What about swapping it out for a buffing pad with a harsh compound?
Though I would then have to poke out the excess from the small holes or blow it out with a compressor maybe.

I had seen a forum talking about chromic acid and putting it in a ultrasonic cleaner, maybe like this

I think they look like Aluminium collars, not Bronze. My wife had good results soaking ours in generic Napisan equivalent.

A stainless steel and copperware cleaning product will do the job
A BBQ cleaner will also do the job to remove these baked grease particles.
These are the same as the inner coating of a well used wok.
Whatever the alloy is, it is quite soft and a scourer will rough up the surface.
This will allow the grease dropplets to key in, and once baked, making them harder to remove,
That's my theory :)

The inset upper surface of the burners is almost certainly steel or ferritic stainless - is it strongly magnetic? The outer ring and body of the burner are most likely an aluminium alloy, at least that's what they're made of on our cooktop. I can't say that we've ever found them particularly difficult to clean, just a run over with a plastic scourer in some hot water and dishwashing liquid, but as Yvan has said, don't let them get too dirty. Some of the chemicals you've subjected them to may have made the job more difficult, I'd be steering clear of any harsh chemical cleaners on the alloy components.

If they really are bronze then I've heard baked on oily gunk can be removed with paint stripper.
I should add I have not done this myself and I would carefully watch the process to make sure its not too aggressive.

I wonder Weiman is what the professional range and oven cleaner used. When they finish, the range looks new. I'm hesitant to try out solvent paint stripper myself, fearing that some of the surfaces will be "bleached" to a slightly different colour, but I'm sure it would work really well to dissolve grease.

I wouldn't use paint stripper while the soiled part is on the stove. I'b be taking it off teh stove and making sure the parts are well washed before replacing them.
