Ive been running this for 20+ years and every 6 months as fuels have
degraded, it needs the burner decoking.
This is normally an hours struggle with chisels and sharp knives and the
like.

The straight cut one ripped through the carbon in about 15 minutes.
A 4mm drill bit bored the carbon out of the feed pipe.

All back and working in record time.
And my hands stayed clean. Since a regular Aga service is getting on
for £100 these days, it's well worth it.
Just a note for any other Aga owners on here.
