The Leifheit window spray cleans windows and mirrors completely streak-free, thoroughly, and quickly. Simply spray, spread, let it sit for a moment, and then wipe it off with the Leifheit window vacuum. For stubborn deposits, quickly wipe with the Leifheit window squeegee, and the window cleaning is done. The window vacuum reliably sucks up the sprayed cleaner from the window pane—without leaving puddles on the windowsill and without your hands coming into contact with the cleaner. The highly efficient spray removes dirt, dust, and grease deposits, leaving a brilliant shine. The 500 ml spray bottle can be refilled up to 100 times with the Leifheit 1-liter concentrated glass cleaner.
