Cleaning interior plastics and door cards

[coupedummy]

Hi
Picked up a stilo multiwagon last week but it's pretty grubby.
The plastics are a very light coloured but wondered what would be the best to clean them up. I've done so much with wipes etc but it's quite ingrained.

Anyone used homemade solutions?
Was likely going to use a soft brush but didnt want to use a solution which would stain the plastic or even make them brittle?
Also gonna do door cards etc

Any help appreciated
