Anyone got any ideas or videos that I can use to remove this stain off the ceiling of the car? I can’t really soak it cause then it’ll sag, and any videos I try to look up on YouTube is just people promoting their cleaning solution which doesn’t have anything correlated to major stains like this, any advice would be appreciated 🙏

Context: a used scion tc, it came like this when I bought it, so idk how long it’s been stained like that for maybe years idk
