Cleaning glass and mirrors can be a daunting task, but by following a few simple steps, you can achieve impeccable results without too much effort. Here's a detailed guide on how to have sparkling, streak-free windows, as well as dispelling a few false myths. Shiny glass in 2 two steps Washing Use a specific glass cleaner , spraying it directly onto the surface. Use a dry cloth to distribute the product, working from the center outwards. It is useful to use horizontal movements in the central part and vertical movements on the sides to ensure uniform cleaning. If the glass is particularly dirty, as in the case of external surfaces exposed to smog and rain, pre-wash. Drying and Polishing Use soft cloths to dry and remove residue. To achieve a streak-free shine, wipe the surface dry with a sheet of newspaper. The drying phase is crucial: act quickly to prevent the cleaner from drying too much, causing unwanted streaks. False myths: vinegar for cleaning windows One of the most widespread myths is the use of vinegar as a natural detergent. Although vinegar has degreasing properties, its acidity can damage some surfaces in the long run, such as the anti-reflective coating of glass and mirrors and the seals of window frames. Furthermore, it is not always effective against stubborn stains or persistent rings. Final Tips Timing : Clean the windows on sunny but not too hot days, avoiding direct light which can excessively accelerate drying, leaving annoying streaks. Materials : Avoid towels that leave lint, preferring 100% cotton ones to reduce the risk of residues and streaks. Attention to detail : Don't forget to clean the edges and window frames, too, where dust and dirt tend to accumulate. By following these steps and clearing up the myths, you will not only make your windows and mirrors shine, but you will also enjoy a brighter, cleaner and tidier environment.
