Within the door cards of my 2014 RRS HSE the silver/grey mesh section has been damaged by a previous valet where water marks have been made.
Does anyone know (a) of a product which might remove/improve the mesh or (b) how easily can these be removed to be replaced by new ones?

Any help would be appreciated

Not good news I bring I'm afraid. You cannot buy just the grills you have to purchase a whole new door card from LR giving your VIN number so as correct version can be made. It costs over £350.00 😱
The reason I know is I made a hole in speaker grille by the footrest on my wheelchair hitting it, I haven't repaired it yet (just tidied) as I cannot justify the price to my better half unfortunately.

I don't know if any product that would clean as required, but another member here might have an idea. John
