Wash my terricloth and microfibre towels and rags used to detail in Dawn, then again in Sportwash. Dawn removes the wax and Sportwash removes everything else and doesn't add any brighteners or softeners that cause streaking. Then just about glass cleaner works well without streaking.

Claybar comes in a lot of different abrasivenesses. Griots sells a clay specifically for windows.

Get the widow actually clean and it will be just like you used rain-x on it.
