First time, used to grill some chicken at 180C

I am starting to fet used to the newest cookware struggling with sifderent stains during the first weeks but this was alot.

1 Is it mostly polymerized fats or somr burnt factory residue i failed to pre-wash?

2 ive never seen suds from dishsoap leave marks like these. What caused?

3 always been curious, these are rhe water spots/mineral residue that people talk about? Are they exclusively caused by hard water?
