Cleaning methods for removal of bound soiling on leather
Abstract
This thesis investigates the removal of bound soiling on leather using three cleaning
methods: Vulpex (10%) in white spirit, gellan gum gel loaded in isopropanol and white
spirit by itself. More detailed studies of cleaning methods for bound soiling in leather
conservation are sparse. With this in mind the aim was to further contribute to already
existing information. The thesis is presented through an overview of the theoretical
background followed by an experimental part. The experimental part was divided into
two phases. First one cleaned several leather mock-ups that were artificially soiled with
synthetic sebum. During the second phase the same cleaning methods were tested but
on two leather objects: a shoe and a messenger bag. These objects were deteriorated
and housed in an old farm building. Due to its environment it had been naturally dirtied.
Results were evaluated through visual observation and microscopy. Following the
results, a discussion is had regarding all the cleaning methods performance. It also
delves into the correlation between preparation-application-results and how it can
affect choosing a cleaning method. The thesis is concluded with Vulpex being the most
effective at removing bound soiling. There are uncertainties if its impact on the material
itself makes it a suitable alternative. White spirit also performed effectively, with some
soiling still left after cleaning. Gellan gum gel had many difficulties and would need
further familiarity with the cleaning method to be accurately evaluated.
