i have a 2001 325ci and it has a sand light brown interior. I was eating some food the other day in my car and got some grease from a burrito onto the arm rest which is sand. it was night time so i didnt bother to clean up until later that weekend. I looked at the armrest a couple days later and the grease had eaten through it and made it discolored like a yellowish goldish color making it real obvious that its been messed up. I used simple green, leather cleaner, orange cleaner, and castrol grease cleaner. None of it will take this stain out this is crazy and my car to me is still in mint shape besides this. Does anyone have any tips on what to do about that stain.Should i buy another armrest for my car or my friends were telling me i could have it redied to match the rest of the interior again. Does anybody know about this stuff and how much it will cost. Please help im a neat freak and this really annoys me seeing this stain everyday and cant cover it up.
