Safe, Simple and Effective Cleaning of Shellac Coated Furniture: are Tensides a Well Motivated Alternative?
Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
The aim of this report is to investigate whether there is one method for cleaning of shellac coated surfaces which could replace the other methods usually used in restorers/conservators workshops, a method which reaches up to a set of formulated standards concerning safety, efficiency and simplicity. Frequent use of organic solvents and materials with unknown, uninvestigated content constitutes a potential risk in a long term perspective, both for the worker and the object. If it is possible to replace these methods with one that is scientifically investigated, this must be seen as a better alternative. The range of different cleaning material has been looked into and from the set of standards one non-ionic tenside has been picked out for further investigation. Theoretically, non-ionic tensides is to be considered as more suitable for cleaning of shellac surfaces since they interact with the surface in a less harmful way than ionic tensides. From cleaning analysis it has shown that the non-ionic tenside Tinovetin® JUN gives pleasing cleaning results equivalent to the ordinary washing up liquid, “Fairy” (in Sweden known as “Yes”). However, from wetting ability analysis it shows that “Fairy” is more powerful. A contact angle analysis showed that Tinovetin® JUN leaves more residue than “Fairy” but the difference is not remarkable. Since washing up liquid contain ionic tensides, it is motivated to advocate Tinovetin® JUN preferably to “Fairy”.
