Based on the customer, suitable cleaners from the existing range were selected for the requirements and brought to the next on-site appointment by our technical consultant. In a specially prepared cleaning situation, several cleaning runs were carried out with cleaners from Eco-Nova. The solvent Topclean proved to be particularly efficient. The wish to continue cleaning with a solvent free of hazardous substances in one work step, however, had to be abandoned. For the customer, aspects such as no hazardous substances and VOC-containing products were more important. The compromise is a solvent with excellent dissolving properties, but with low volatile properties, so that subsequent cleaning is necessary.
