What about a window?

Crush up newspaper

microfiber cloth and water or a water/ Vinegar mix

First, take an equal amount of vinegar and water and mix them together in a spray bottle. White distilled vinegar will work best for this. Then, spray the solution on your windows and let it sit for around two to three minutes. Lastly, use a gentle cloth to wipe away the cleaning solution and avoid any streaks.

I use half and half plain white vinegar and water, spray on and wipe with a microfiber cloth.
