Why does NEWSPAPER WORK WELL TO CLEAN GLASS......????

Question

When if you try to clean anything else with wet newspaper you would see black ink streaks?

Answer 1

it's actually the chemical mix in the ink that cleans the glass  

Answer 2

I have no idea but keep using it because it works so well ^^. I think it's because of the type of paper which sucks up the window cleanning liquide and doesn't leave any streaks.
