any tips or secrets as to best clean my head lining on a 50 year old classic ford,its white and has staining from 50 years of fingers grabbing the door jam, tried all sorts but no too much joy.
I am guessing it is vinyl? What have you tried so far? My choice would be baking soda mixed into a paste with water and rubbed gently across the stained area with a brush. Do not soak the marks and wipe off excess.
