When I clean a mirror with glass cleaner and a paper towel, I see a bunch of little specks left by the paper towel. I've tried using hand wipes and newspaper, but they both seem to do the same thing. Is there something else I can use that doesn't leave stuff behind?
Just use a regular cloth, such as a towel or even a T-shirt. Rub on the spot that needs attention (I do it in circles), and soon your spots wll disappear.
Believe it or not, newspaper is really great for cleaning windows and not leaving streaks. You can either just use the newspaper with your cleaner, or you can wipe the window with the newspaper afterwards. You can wad it or fold it.
You could use table salt along with tissue paper to clean and then use a drop of water at last so as to remove the leftovers too.
Use liquid handsoap, rub onto mirror and use the palm of your hand to move it in circles until the entire mirror is white and creamy, then use a regular hand towel and slide from left to right once , then move to the next clean part of the towel and do the next left to right strip.
Don't worry about the little white line left between strips, do these after the mirror is completed.
I usually do this each time I'm changing hand towel in bathroom. It's gives superior result compared to any other method I've tried.
Try a coffee filter, lint-free paper towel, or a microfiber cloth.
