Not sure if anyone has experienced this, in fact I personally haven't but have been asked to comment on the problem from afar.
A very thin white dust has formed on the inside of a steel offset smoker ( its a budget line )and is relatively new but certainly used a few times . No Smoking medium was used. The briketts used were coconut shell with potatoe starch binder 2%. We know the binder would have disappeared to nothing so we dont feel thats the cause. The ash is light brown and definitely not bright white. There would have been minimal smoke from these briketts.The Fixed carbon is 76%. This is the briketts at the end of a long Low Temp cook, still pretty much intact and still giving off good heat.The problem with the same batch of briketts does not occur on BigBrand enamel ceramic lined smokers (PBC) nor have I seen it when Ive used the Briketts from the same batch on my Weber kettle.The dust has no smell in fact Im assuming it must surely have settled on the cooked foods without any reaction nor visible signs but as you can see from the picture it looks like a can of spray was appled to everywhere where the food wasnt. Im speculating that it may be a reaction to the metal responding to thermal heat in an odd way- but Im no metallurgist. I know certain chemicals are added into molten steel to give strength but thats about it . I also dont know what is used to clean the Grill inside but I expect knowing the users it is cleaned very regularly. I read somewhere some cleaning agents contain ammonia and this can remain invisible until it comes in to contact with heat-but this was an answer on a gas appliance forum. Another hint to this is the back right of the main chamber appears less white , almost with a cut off point so maybe if it is cleaning agent this was the last place cleaned and whatever used was then diluted.. That said the chimney exit is also the right side of the main chamber so smoke travels from R to L below and then circulates above from L to R exiting R through the chimney.The powder wipes off easily but its a job no one expects.It's talcum powder fine. So heres the pics I've been sent . If anyone has experienced this or has any hints as to cause id be happy to hear... Paul
