You will see how the glass will be very shiny and without streaks .

The newspaper leaves a kind of invisible layer that prevents the accumulation of dirt. However, it is important to choose old newspapers to prevent the ink from staining the windows.

For more stubborn dirt, however, it is necessary to use a sponge and scrub well from top to bottom. Finally, wipe again with a microfibre cloth.

A further tip: clean the inside of the window with horizontal movements , and the outside with vertical movements . By doing this, if streaks remain, you will immediately know which side you will need to clean again.
