Black dirt on floors

Has anyone ever had issues with black spots on the floor? We have while floors and after cleaning them, black flakey spots appear from nowhere and track all over the room. The “dirt” gets stuck to chair wheels and just spreads. There is no obvious place the black dirt is coming from. I have a new operator stool, so I’m sure that isn’t the issue. As soon as I detail the chair wheels and floor, the spots return the next day. Please, has anyone else dealt with this? I feel like it’s some sort of oil….but I have no clue where it could be coming from and it’s driving my insane !

Even though your chair is new, the only thing I can think of that would cause oil of any kind is the rollers on the chair. I would imagine they are greased to make them roll easy and after moving around a bit, excess grease may flake off. It would drive me crazy too! This is the only thing I can think of!

It’s from prophy paste. If you notice it on you after polishing, then it’s getting on the floor as well. When the chair rolls over the floor then it turns black. I now suction while polishing and use less paste. This does cut down on how much flings put of the mouth.
