Glad I stumbled across this post. Found out last weekend that my 3rd brake light seal had given out and began to leak. Anyway, I didn't realize it until my girlfriend asked me about water marks on my headliner.
Anyway, sure enough I have gross Brown water marks above my back window.
Any recommendations on how to go about getting these out without releasing the glue on my head liner and causing it to sag? Picture attached. Can see water mark above plastic on rear pillar where seat belt is housed behind door and most obvious Mark is below clothes hanger hook.
