Clean your windows
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.
