I noticed after 1 year and 16K miles that the headliner is becoming dirty especially on the B pillar on both front doors (probably from driving with windows down). Anybody used or know of a good cleaner????
I took my ML in for servicing relating to the sun roof and they got grime all over the trim (which really pissed me off since the ML is only 6 months old). Anyway, I used Simple Green and it removed the grime marks without a problem. I repeated the process with a wet towel (water) to ensure that the cleaner would not discolor the fabric. Hope that helps.
