The wood trim in most vehicles (some Mercedes Benz model’s use real wood) is protected with a urethane clear coat, polyurethane or a thin lacquer, which is very easily scratched. Remove scratches with a fine polish (Groit's Fine Hand Polish) clean /protect with a chemical cleaner (Klasse All-In-One or Zaino Z-AIO) and then buff with a clean 100% cotton towel
Note-If your finger nail catches in the scratch then it’s too deep to remove
