We clean using four techniques: classic, pressure, demineralized water, and nanotechnology. We most often use the classic technique, which involves mechanical cleaning with a special washer using water, chemicals, and squeegees to remove excess water. In pressure technology, a jet of water under pressure is used to remove more stubborn dirt or to rinse glass. The most glass-friendly technique is the use of demineralized water, as this water is purified and free of sediment-causing minerals, allowing us to wash without using chemicals. The fourth technique, nanotechnology, is a modern and highly effective method of cleaning with the addition of a special impregnate in the form of nanoparticles, which leave an invisible protective film on the surface, thanks to which dirt and dust don’t settle as quickly as after conventional chemicals.
