Is there any special way to clean the inside of the glass if tinted with aftermarket film to avoid scratches? I think the tint guy told me to use a wet rag, but that didn't seem too effective on stuff that got stuck to the glass.
I use Stoner's Invisible Glass and microfiber glass cleaning cloth. You want to avoid Ammonia products like Windex. Stoner's is safe for tinted windows. I've had no problems at all. $4 at Walmart.
