keeping the door panel cleaned during service
 

For those of you who have the light color interior, how do you keep the door handle and panel clean during service by the shops/dealers?

I am very concern about those greasy hands on the alcantara materials as it is so difficult to clean.

I normally put a towel to cover the seats, but not sure what to do with door panel and door handle.

I wipe (or wash if needed) my greasy/oily/dirty hands before touching the car after servicing it.
