Innovative foam-based cleaning concepts for historical objects

Abstract

We developed a new, innovative foam-based cleaning method with which the amount of detergent can be reduced by up to 90%. In addition, foams generate physical cleaning mechanisms, namely imbibition and wiping. The combination of imbibition and wiping is so efficient that it is sufficient to simply let the foam sit on the surface for a while before removing it by vacuuming. No additional mechanical action is needed! This publication describes how we managed to clean the historic carriages of kings and emperors of past centuries in the “Marstallmuseum” in Nymphenburg Palace in cooperation with the “Bavarian Administration of State-Owned Palaces, Gardens and Lakes”.
