Barry,

Leave em alone it won't hurt and I doubt whether you'd notice the
difference.

I am restoring a 5" Duchess the boiler of which is in generally good
condition. However the flue tubes, which are about 15/16 ins. I.D., are
coated internally with a layer of hard, black carbon. I have given it =
the
usual flue brush treatment which produced clouds of black dust but a =
hard
layer about 1/64 ins. thick remains. I have tried fitting the flue brush
into an electric drill and giving the tubes a few minutes of rotary =
action
to little effect. I am wary about trying anything more aggressive as I =
have
heard quotes of over =A32000 for a replacement boiler. Any ideas anyone?
