What is the best cleaner to use for a CTS sunroof?
Thanks for the help.

I use Window Finish by Finish First for all my glass cleaning. No streaking and the smell is not bad.

I use Stoner Invisible Glass cleaner. I get it at my Ace Hardware store.

I use the GM glass cleaner. Best stuff I have ever tried.

Windex fixes everything.

Windex fixes everything.

Someday try a non-ammonia glass cleaner (such as the Invisible Glass or GM's mentioned above) side-by-side with Windex and you'll never go back.
