Dear Colleagues: I would be most appreciative of any and all advice on solutions to mop and clean the floor of my main collection storage. The room holds fine art, natural history, and skeletal material. All are on shelves, partially boxed; all shelves covered completely with polyethylene sheeting. We recently moved all objects from the floor and all crates have been removed. When I saw the open space and the filth problem, I knew I needed solutions. As usual, I have a crew lined up for the week of Aug. 18. Time is short. Any suggestions, will be so helpful. Thank you in advance. Kristi Alexander McClung Museum [log in to unmask]
