I had dirt/stains around the furnace outlets in my 02 Journey. I have removed 90% with soap and a mild bleach solution. I've seen on TV an advertisement for "Vince" (short for Invincible). My concern that it may attack the bonding agent that holds the headliner up. I want to clean up the last of the shadows left.
Anybody used Vince on the headliner with success? Any other cleaners with success?
