Need help with removing liquid stains from interior plastic

[azi90]

Hello,
Bought a used car which has some liquid stains at the interior plastic of door. I have tried using Interior Automotive cleaners and protectant but it didn`t make any difference. I have also tried using scrub and elbow grease but no luck. any suggestions?

Sorry you didn`t get any responses.
I looked at the pic you posted, but it is difficult to determine exactly what type of chemical in the liquid caused this "stain". My best guess, and it is just that; a guess, is that it is a petroleum or solvent-based liquid that has permanently etched the plastic.
You did not mention if you used a Mr. Clean Magic Eraser pad to "clean" this area by scrubbing it. While I do not recommend this because it will abraid and scuff the plastic panel, it MAY remove the stain, but you are left with a visibly scuffed panel.
Which is worse: the stain or a scuffed panel... You decide.
You might try Goof-Off (not to be confused with Goo-Gone citrus cleaner) but it is a solvent that may remove the coloring from the plastic along with the "stain", SO BEWARE!.
One solvent cleaner that MAY work without damaging the plastic is Rust-Oleum`s Krud Kutter Ultra Power Adhesive Remove. It is kinda like Goo -Gone on steroids, so I would first test it in an inconspicuous spot on the plastic panel first, like the underside where the stain may be.
Hope this helps.
