When ever I have a dump in anyone elses toilet there's never any need to use
the toilet brush afterwards.

In my own newly installed pan, however, I always get a mud-like adhesion to
the surface which takes a bit of scrubbing off and re-flushing. Is there
anything I could use to "season" the pan surface (Like you do with a new
Wok) so the ****e doesn't stick so readily?

I can confirm this is a real problem and not notably related to diet:-)

Our house has the benefit of 4 toilets (don't ask) all Twyfords, all
installed by the same builder and during the same re-development. 3 are
fine. The 4th. has exactly the problem described by the Major.

It is clearly a cheaper version and may simply suffer from inferior
glazing.

I think replacement is the most likely solution.
