Non-stick becoming 'stick'

Hi Andrew,

Enjoyed your report on non-stick pans.  My wife and I have a set of the Tefal brand Jamie Oliver professional series pans (with the red dot in the middle).  Now the red dot has all but disappeared and they have lost their ‘non stickiness’ so I suspect that they are coated with ‘stuff’ (oh yes they have been put in the dishwasher on occasion).

Anyway, before we ‘ditch’ the pans is their any suggested method to try and resurrect these to some level of usefulness.

Best regards and all the very best for xmas and the new year.
