I dive into methods and products I have used when cleaning interior/exterior windows. I talk about alcohol, Invisible Glass, HyperClean Glass Cleaner and good old Dawn dish soap with water and a squeegee! You can get alcohol from any pharmacy. Just dilute it 5 or 10 to 1 with water. Hyper Clean can be purchased directly online or from our local distributor - Shawshanked Detailing. Just walk in his shop Monday - Thursday 9 to 5. Check out this small squeegee I bought on Walmart.com.

Whatever you do..do NOT use Windex! It is NOT for automotive windows. Also, use the two rag method - one wet, one dry. Go in a vertical motion for exterior and horizontal for interior. This way, you could tell where the streaks are when you inspect your work in the end!
