No clue what the stain was. Noticed it while driving wifes car and she had no clue. I have used the adams foaming interior cleaner, with the black stiff bristle brush. Sprayed let sit scrubbed with brush and it is still hard as a rock.

I have a cloth cross hatched passenger seat. The stain is gone but it left a very hard spot feels like something dried in it and its a solid spot feels like wood. How would I get this softened up and removed.
