Simple household products that you find in supermarkets work well. They are mainly purified water and vinegar.
I have used thisetgod though in the F since 2015 and it works well...
Prepare the glassy using kitchen roll, soaked in Alcohol to remove any greases.
I then use Rain-x inside and out to seal the glass.
Once dried and buffed I use a dedicated MF cloth that stays in a sealed sandwich bag in the glove box for interior glass.
The last point may seem a little OTT, but with glass Is the most important point. Any contaminants from skin moisturisers for example, will bugger up your nicely prepped glass.
