An expert will hopefully be soon,

but in the meantime I would have thought sandpaper would have been too rough. Something like scotchbright or similar scouring pad instead perhaps?

I used fine (320 or 400 I think) glass paper on the two I've done this year. It's possibly not requried unless the clutch has been slipped a lot and the flywheel is well polished - but you don't want to have to take the box out again..... Make sure you give it a clean afterwards with a paint brush to get rid of any bits of grit, and then meths to clean off any greasy fingerprints, or the protection oil on the clutch cover itself.

Is it illogical? It must be Citroen....

im more concerned about putting the plate the right way round to be honest
a quick wipe with thinners is all i would do (brake cleaner these days as the substitute)

Unless the flywheel surface is deeply scoured, I would leave well alone. If you roughen the surface, all that you will do is wear your new clutch material faster than normal. The smoother the surface the better.

There is some point to removing glaze from oil lubricated surfaces, such as cylinder bores, but a clutch should have a smooth, deposit-free surface. Remove any oil / grease, but apply no roughening.

Just changed the clutch on my pug 405TD. Just cleaned the flywheel with carb cleaner, it was quite shiny. Clutch is now lighter and very smooth on take up. And I thought cambelt changes were bad....
