Whenever I take my dog somewhere in the truck he usually slobbers up the side windows. So instead of using up my paper towels, I found out that newspaper works good for cleaning glass, along with Sparkle or Windex.
1000's of homeless guys around the country can't be wrong.
There's a much better and much FREE-er way.....
best way to clean glass for sure
Try ammonia, it's way cheaper than "glass cleaners". All Windex and Glass Plus are is watered down ammonia that is colored and given a cleaner smell.
