Good point.
I'm quite sure it was brake dust because during COVID 19 lockdowns everything was the same (heating etc) but streets were void of cars.
Then I've read some scientific article about brake with pics and it looked exactly as what I got inside my house.
I can't conclude 100% it was it (or just it), but it seems to be the most probable cause along tires.
