One of the Autoglym products that I still use is their Glass Polish - excellent stuff.
IMHO, it makes a big improvement in how rain is cleared,
Big fan of Autoglyms Glass Polish
Couldn’t see the point of it at first many years ago until someone told me to also use it on the wiper blades as well after polishing the windscreen (don’t use a nice cloth as it leaves black marks) and boy does it work
