I wanted to get some opinions on help determining what this is. I think it's rust. This showed up within 2 months of ownership on my Drolet HT-3000 stove last winter. It rubs off brown onto a paper towel with vinegar. I contacted Drolet and they told me to pound sand, and go get some stove paint. They said it's not rust, and I must have smudged something on my stove. I don't ever put anything on top of my stove or near it since it's insanely hot. It's pretty unsightly right on the front of my new stove. This stove is inside in my living room.
This is the picture I sent them.
