Hello all,

My wife's 2015 Accord EX is parked outside. We are in the Atlanta Georgia area. I am meticulous about keeping the car clean. Along the inside edges of the doors trunk and hood is a black line of dirt or oil. Does anyone know what causes this and how to safely remove? Thank you

 

I would suspect it's where the gasket meets opposing shell. Black rubber, sun, and dust lead to a mark. Strictly my speculation.

good luck

 

thank you
