I have some memory that if you were to chuck away an electrical appliance
you should first cut the plug off.
However a cut off moulded plug itself seems dodgy as it could be plugged
in and have a live connection.
Take the fuse out helps but kitkat wrapper.
So just put the whole thing in the electricals bin at the tip?

Secondly, I have a 4 way extension lead up high under a roof in the dry,
but outside.
It is getting a bit stiff for plugging in and out, which I assume may be
oxidisation of the connectors over time (years).
Is there a suitable lubricant?
That is, something electrically safe but not just a drying solution like
WD40.

Google electrolube, Farnell and the like stock them. You will get a smaller quantity maybe at your local model shop, model train enthusiasts use it to lubricate pickups, but may not be any cheaper.

I use a "contact spray" that either came from Screwfix or Toolstation, I
think it is good to use these for low voltage and maybe low current
contacts such as electronics kit and automotive switches, but TBH for a
mains "spreader" I would be almost as happy with a silicone spray, also
available from SF, TS, and periodically Aldi/Lidl. The stiffness there
could be from contact oxidation, but IME is just as likely to be from
deformation of the thermoplastic structure giving you plastic on plastic
or plastic on metal sliding friction.
