Mavro Italia, together with its sales partner Serisolar, has applied various products to restore the appearance of polluted and dirty trains at a transport company in the north of the country. The exterior has been thoroughly cleaned and stripped of brake deposits, copper particles and graffiti, and then permanently preserved with the permanent coating Nitocoat, which protects the train against various soils and graffiti.

In addition to the outside, the inside has also been overhauled. Seats on the train have been cleaned with ink, marker and dirt removed and then treated with Nitoguard Textile, which provides a water and dirt-repellent surface.

The floors in the train have been pre-cleaned to treat with Floorguard Polycryl, a hard-wearing water-based polymer wax. The windows are also cleaned on the outside and treated with a protective nano-coating.
