How to clean an old drop ceiling with tile & metal dividers?

by Barb

Our ceilings in living room & dining room are pourus, with metal dividers, both discolored just from years of being up there. How do I freshen it all? No budget for replacement. We have squirrels in winter, so I really do not want to remove tiles to clean them as who knows what "yuck" is up there! Do I paint? Can I wash or will they be even worse and streaky? What about the metal dividers: paint, wash, or another option. I will appreciate help from those of you with this issue. In Western New York, it is cold, and furnace runs a lot in winter which the discoloration is partly due from as we heat with fuel oil. Thanks for ideas---I am "grateful Barb"
