First time home owner here. I stuck these vent deflectors a month ago on one of our vents and I removed it today for some other reason. I noticed these stains that looked like water stains but I think it’s actually something that is growing - maybe unfortunately mold or something. I need help in understanding this situation and possibilities of this happening. Please share your experience or knowledge related to this issue if you can.

Thank you!

EDIT: Mystery solved - this seems to be the result of some chemical spray during cleaning. Not concerning.

    Does the stuff scrape off? What’s the result look like if you give it exactly one good scrape with a flathead screwdriver?

      This is how it looks after a bunch of soap and scrubbing with a new toothbrush.

      This feels chemical for sure. Mold probably would have come out by now I think.
