Cleaning Gas Cooker Burners

[davidmh]

I have Plastimo Neptune gas cooker, the hob burners sometimes do not light all the burner outlets. I have tried scraping the cast iron burner top and poked out the burner holes and it is better but still not perfect. Since the Cast Iron head just lifts off I was thinking is there any solution you can dip the burner in which will dissolve the carbon build, some of it looks like rust.

Wire brush worked dor me. Get them really clean.

There is no shortcut, they are cast Iron and they do rust and the rust causes partial blockage. Modern burners are aluminium, maybe someone is producing aluminium replacements (would be good but I don't have a clue).

I think i used a drill bit the right size for the holes. Persist mine went from.awful to great.

I also used a drill bit to get holes back to size which totally fixed the burners.

You can get gas burner files in a little set, but use a little bronze brush from a plumbers merchant and if you have power, vacuum on as you go.

If it's blocked by rust soak it in some acid like vinegar or HCI for a short time wash in fresh water afterwards

Don't just clean out the holes, there's supposed to be a small gap all the way round that maintains a small flame under the holes to prevent the flame lifting off.

Thanks for the replies, Stenmar has a point and this gap is created by the shape of the indents in tha casting. The idea of dipping it a mild acid to dissolve the rust is good, would Oxalic acid have the same affect, it seems to to remove rust stains from GRP.
