Invisible Glass is a great suggestion. I've used it, and thought it worked very well... but since then I purchased the GlassMaster and window cleaner from Griotsgarage.com - the cleaner is excellent, and you can almost do the rear window from the front seat.

LesteR723, nice catch. I wish I had seen this before I got the Glass-master-pro unit. This one looks like it would be a lot cheaper. Its smaller though but I like the velcro that holds the wipe in place.

 

Old detailers trick - Use newspaper to clean the windows. Streak and lint free.

New trick - Polish them with Mr. Clean magic erasers. They work great to get those persky dragstrip numbers off as well!
