mmmm Just a thought,

Is there any chance a 'hot purge' in fre O2 at high temp can 'flush' the
sensor ?

ie. Remove sensor from exh manifold, put in oven with liberal feed of pure
O2 and heat to exhaust temp for a period of time, perhaps cycle through
temp range whilst flowing o2 over it...

I'm guessing this might flush out some/most contaminants - anyone in a
position to try this - or interested ?

I wonder if someone has an oxy torch, can make up a little pipe, close off
the end, heat it with the oxy (not too hot), fill the pipe with O2 from
the oxy tank and let it cool down filled with pure o2 ?
