Mine runs out end of May so till then, it should all clear up.
Good garages use seat covers so you can request them on your test.
You can wrap steering wheel in a cling film and same on gear knob.
I would do that.
Wiping points of contact might be difficult as they have to test various points like seatbelts, seats ect.
You would have a lot of wiping. Might as well wash the car inside and out.
Thinking of it now, it should be required by government for MOT station to do so. Lol
I wouldn't want it done by them.
