Mitigation strategies based on in-situ application of titanium dioxide nanoparticles on glazed tiles from Casa da Pesca, Quinta do Marquês de Pombal, showed that the so-far developed treatments promotes a desirable detachment of the biofilm and there is evidence that it may have a preventive effect.

The tests performed with task-specific ionic liquids developed at VICARTE also proved the effectiveness of the cleaning product in removing corrosion crusts of glass surfaces. Even when in direct contact with the ionic liquids for a long period of time, no alterations of these surfaces were detected.
