The windows are only part of the story.

There are many strong cleaners that will work. But they will take their toll on window seals and any part of the interior they contact over time. Some also create a surface that attracts pollutants making you use the product more often.

I've gone through an amazing (stupidly long) list of window products over the years. The absolute best combination that I've found is:

- Plain water with 5-10% alcohol.
- One of the sponges with a nylon mesh on one side.
- Microfiber towels.

Get a bottle of rubbing alcohol, etc. from the drug store and mix with water. Use an old Windex or other spray bottle. Dampen & squeeze the sponge with tap water before you begin.

Spray the sponge with your cleaning solution. Use the nylon side on the windows. Then wipe dry with the microfiber towels. Buff slightly afterwards with a clean dry microfiber towel.

This won't hurt your seals or upholstery. It's cheap. It won't set up a condition that attracts pollutants after cleaning. It happens to be environmentally friendly (if that matters to you). I get better, more streak-free windows than I've ever gotten with any commercial product. You'll find this is what a lot of the concourse competitors use (those who don't use their cars except for showing may drop the alcohol to 0-3%).
