During my internship with the University of Cambridge Museums I developed a guide on cleaning and caring for limestone objects to support small, local museums. The guide describes good practices in limestone object cleaning. It outlines how limestone objects can deteriorate and it aids in the decision making on whether an object needs cleaning, to what extent, and what technique might be appropriate. The guide also gives advice for the storage and exhibition of limestone objects. Additionally, it includes information on where to get further help and support.
