After printing, I am left with a very fine dust 'film' on the glass around the item I just printed. It wipes off reasonably easily with kithchen paper, but it does limit the bed adhesion I get when Sequential Printing a number of parts. Does anybody know what this dust film is and how I can minimise or eliminate it?
I'm printing with Real Filaments Black PETG directly onto very clean borosilicate glass sheet, at 250C/80C, lid open. The glass gets a wipe with a clean, damp cloth before every print. After the print is finished I am left with clean glass under the part, but a dust film on the glass around it.
The printer is sited in a large, clean cupboard in my house. If I leave the printer with the lid open for a few days without printing I barely get a speck of dust on the glass.

Thoughts about Raise3D, 3D printing and making in general.
