For this project, window frames and sills were thoroughly cleaned and treated in collaboration with Marks Cleaning. Objective: to remove dirt and restore the surface to a clean, durable appearance. The cleaning was performed using Uniclean Low Foaming, an effective all-purpose cleaner for professional use. Isopropanol was then applied to completely remove any remaining dirt and residues and to optimally prepare the surface.

After cleaning, the surfaces were treated with Nitoshield. This coating restores the color and provides a protective layer against new dirt and weather conditions. The result is immediately visible and lasts longer. The combination of cleaning and protection creates a durable end result that requires less maintenance in the long term.
