We have people who clean regularly so I don't think that ever happens. Usually someone with a particular interest in an area takes the initiative if they want something cleaned up, although it usually runs into some political issue along the way. You know, you can't get rid of the choir robes (that many people in church don't even know exist, and that haven't been used in more years than anyone can remember) because some member who died 25 years ago donated them and their granddaughter (who hasn't been seen in years) would be so deeply offended if we threw the gift away. So the choir robes continue to take up prime storage space while the things that are used weekly are squashed into small awkward spaces.
