Due to me doing some wiring and rewiring of my dash cam and rear cam, the A-pillar covers are now a bit dirty from being touched with greasy fingers.

The light grey/white/beige variant.

 

How would I clean them properly without damage?

(I would prefer not to dismantle them again for cleaning)

 

Same for the interior headliner roof?

It is some cloth glued to a hard foamy stuff and hard paper/plastic?

I suspect this must not get too wet?

I used this stuff to great effect 1 litre last ages
