Cleaning and sanitising treatment
The outdoor paving in Trani stone, with a polished finish, yellowed due to the corrosive action of time and vegetation, was washed by specialised technicians with Algaenet by Fila Solutions, a rapid anti-algae detergent, which removed dirt in depth, without damaging the material, and sanitised the surface; inside, the paving, ruined by the wear and tear of time, was restored by washing with PS87 PRO, a concentrated biodegradable degreasing detergent effective against stratified grease.
