When I wipe my white vinyl siding with a damp brown paper towel, the towel becomes white, indicating that dust is coming off my house. It seems to indicate that vinyl dust that is constantly being released from my siding, which I assume then gets into the air and soil around my house. Has any research been done on this issue?
Yes it is the siding being broken down by the sun. It is better than the land fill.
