The Fenix Palace on Wenceslas Square has two main entrances, one of which is formed by a granite staircase. The rough granite surface of the staircase has not been maintained in any way for decades, only wiped by the cleaning service. In the middle of the staircase is the door to the restaurant's kitchen, the staircase was dirty in these places with grease from the shoes of the staff passing by. In other places on the stairs, there was glue residue from the once-glued carpet. Using the Narran ROD1000 pulsed laser, we cleaned the staircase without having to close the passage and without interrupting the operation of the adjacent theater and cafe. www.lsrservices.cz
