Luce, one of the cleaners, told me that it's better to use newspaper sheet to wipe glass door/window than a piece of cloth. She said it makes the task easier and glasses would look more cleaner more shinier. I was skeptic at first.
I thought the dried ink on the paper would somehow melted and stuck on the glasses. Who knows? In, another cleaner, showed me how it was done. Unbelievable. It works.
Just use it like you use the wiping clothe. Spray some cleaning liquid on the glasses. Scrub it with the paper. Scrub harder on stubborn stain. Voila! The glasses become clean and shiny. Believe me. It works.
Why don't you try it yourself? Don't forget to tell me the result.
Note: This technique only work on dust free glasses. Meaning, it won't work on glasses that have thick dust layer.
If you want to clean up the dusts, just use a vacuum. Dust won't stray away and it fast. After that, you could use the tip above.
