That product is just your generic otc wash soap. Nothing great or really terrible about it. The best otc product in my opinion is Meguiars Gold Class Car Wash.I have no experience with this product, but I would rather use a dedicated wash followed by a dedicated wax. Just my .02 worth.
That is very true; the type of toweling (whether disposable or a reusable cotton or microfiber material) can make a massive difference in results with regard to a film or streaks left behind.I found for windows it's not so much the product, stoners is great, but the material you use to clean the windows with the glass cleaner. I use some new microfiber cloth the size of a face cloth that works great.
