| Résumé : |
For industrial component cleaning, a large number of different cleaning concepts are implemented around the globe. Most recently, surfactant-free products have been introduced with great success. It is high time tohave a closer look at their application characteristics in comparison to traditional surfactant-containing products and to carry out a detailed evaluation for the potential user. |
