<p>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”.</p>
