Will the pole leave marks on my ceiling?

Like the base, the ceiling dome has a soft, clear silicone ring around it. If this is kept clean and free from dirt/dust there is no reason it will mark a plasterboard or cement ceiling. We recommend wiping it down with baby wipes before installing to ensure it is clean and prevent transfer of dirt onto ceiling. If you have not cleaned the dome and it has transferred dirt onto the ceiling it can be cleaned off with sugar soap.
