There are all of the above. We have a large number of pieces which vary from iron pieces to mills, to gas pumps and most everything else. Some of the pieces have paint, others, I can’t even tell if it does due to exposure to weather. Nothing absolutely must retain motion though. There are a wide number of levels of deterioration and layers, but it is a large number of items (above 50). I am really just hoping to get a general “approved cleaning supplements” idea within a small budget. Many objects may be deaccessioned, but should be cleaned first regardless.
Any help is greatly appreciated!
