I hadn't cleaned my windows for, well, let's say at least a year but probabaly longer. I was totally blind driving into the setting sun the other night and decided it was time. It took half a roll of paper towels and some glass cleaner but WOW, I can see again. It was like driving in a permanent fog bank before, and now it's crystal clear. This may be a "duh" kind of post but think of it as a PSA to those others like me who spend more time working under the hood than cleaning the interior. I'm going to start doing this every few weeks, it's so nice.

 

Be careful as to what you use on tinted windows though!

 

I stripped my crappy old tint off the first week I had the car, way back when. But yeah, some cleaners will strip it right off for you. Like Simple Green, I believe.
