After cleaning it with water, and drying it off, use some news paper and that will take out the streaks and hand prints. Some people also use a squeegee.
I spray some glass cleaner on a paper towel. I spray it in the kitchen, and by the time I take the three steps to the tank, it's soaked into the rag enough I'm not worried. Then it's a piece of newspaper to clean the streaks.
newapaper is supposed to be the best but i've never tried it yet.
so far i just spray windex on a paper towel. any left over steaks are wiped away with my sleeve. :duh:
On the inside I find that the best way is manually with a razor blade. I use the big ones that come as an ice scraper! All other methods have acted to scratch my glass! I also only need to clean my glass twice a month.
On the outside I use a wet paper towel, followed by a dry one to remove the water from the wet one.
Water fine. Either spray water on the glass or take a wet paper towel and clean off the glass. Then dry it with another paper towel or just let it dry by itself. Use a dry newspaper and take out the streaks.
