    If that was you first time of use then that’s a big no. Even after many uses it didn’t look like this with my roccbox. It gets a bit dirty, yes but not like this. Perhaps the burner is damaged. Looks like the fuel is insufficiently burnt.

    Mine also looked like that. Was never a problem.

    Would this be different for everyone else. Amount of debris that end up on the stone. My koda from 2 half years ago also have a “used stone look” but I can’t remember how it looked like after the first cook.

  5. Yeah mine looked like this too from the rolling flame. I also did burn bits of my first pizza which adds the the black soot. Really need to see your pizza’s!

    Mine looks like this. Can just wipe it off

  7. CrisbyCrittur

    Mine’s always looked like this after use, burner is fine. I just use some Barkeeper’s Friend on a damp cloth to remove it every couple weeks.

  8. yep. not sure if it’s normal but that’s what mine does

    Mine didn’t look like this after my first cook. But I’ve used it like 5 times now and it looks like this.

    If it’s gas fired, it should not look like that unless the burner is setup wrong or your pizza was literally on fire.

    Was there some sort of plastic shipping film you were supposed to peel off?

  11. another thing to remember is that propane is a dirty gas. hank hill lied to us.

    I just got one and it did the same, but haven’t had any functional issues 🤷🏻‍♂️

    Mine looks the same. Unfortunately burning gas is a pyrolysis procedure which, unless under ideal condition, produces soot.

    You can check the regulator – most of the burning issues of propane / butane come from incorrect or insufficient oxygen mix ratio. I you can go down the rabbit hole of testing different regulators, but then you’d also have to consider the gas pressure from the valve of the tank etc etc.

  14. What color is your flame? Optimal combustion would be blue. If it’s yellow or red the air / fuel mixture is off causing the soot.

    Check manual and see if there’s any adjustment for that inside by the burner.

  15. A sign that it’s getting up to temp properly. Wipe it off with a wet rag between uses so you don’t get soot everywhere

    Just searched Reddit for “Roccbox soot” because mine looked exactly like this after the first cook tonight and I was concerned it was a problem. Burn seemed fine, nice rolling flame, and the pizza cooked fine, but yeah it’s a sooty mess. From the replies in here I still can’t tell if this is normal or not lol

    Edit for anyone else that finds themselves wondering about their sooty Roccbox – it appears that the Roccbox gas burner was intentionally designed to have incomplete combustion, which is what causes the sootyness wherever the flame reaches. The reason they designed it this way was to get the “rolling flame”.

    Can you adjust the air/fuel mixture? This happens when my griddle is out too
