Ok all I have tryed to remove this stain in several different way ,everything from wiping to scrubbing with a tooth brush and products such as ,Turtle Wax Carpet/Upholstery Cleaner , Griot's Garage Carpet/Upholstery Cleaner, McGuire's carpet and upholstery cleaner, wool light and water, Dawn Dish soap and water to no avail. Its where my elbow rides on the door panel (I'm 6 foot 300lb so I'm a big boy, reason I bought a challenger and not a tin can Camero of Mustang lol) I'm sure its skin and body oil but it's just not coming out. I have 4 picks 2 before and 2 after to days scrub. I'm half way thinking of getting a wire brush and grinder. this spot is driving me nuts. 2 photos are before todays scrub and 2 after, But I've spent all week focused on this spot cleaning it. Any ideas? And thanks nuke the Wool light got the dog slobber up.
Okay, so its on the plastic door panel, i was thinking it was the vinyl/leather arm rest down below that...well, that is very reminiscent of cleaner wax stains on exterior trim, and if it is the same type "damage" as what cleaner wax does to trim, you won't be able to remove that spot per se, you'll have to mask its discoloration with a trim restore type product.
Unfortunately, if it does need some sort of trim restore or trim black product, I don't think you can count on any of the standard stuff we use on outside trim because it's all just a topical treatment at Best, and certainly will wear off from repeated contact with your skin.
I don't know man, it sounds like its gonna be a pain to fix or a pain to live with, pick your poison
Now that's all supposition on my part, and more me thinking out loud than anything. But if everything else you've tried hasn't helped, what else can you do...
Anyway, I'm actually cleaning my Challenger this afternoon too, so I'll keep thinking on it and reply here if I have any bright ideas
