From an employee at Cedar Point during cleaning week this season I can tell you all that we cleaned (Me and my crew did most of it).
Low Zone areas of the track including the removal of all trash, leaves, and cig butts you could fine. Wash down of the station platforms and cue lines with power washers. Cleaning of all hand rails and steel gates. Washing down of trains/polishing of stainless steel. Plus anything you could think of cleaning was cleaned.
I took great pride in cleaning the Force this year cause I am working the big blue all season this year. Hope to see all of you some time this season.
