Is it my imagination or is the latest windscreen glass harder to clean?

Not a big deal but using the same products as always it seems harder to get the faint rain blob marks off - more elbow grease needed.

 

(Having said that, I am still amazed at how easily the bodywork paint cleans - and this on my first white car for over 35 years!)

I will ask te nice Polish lads that do mine eah week! They havet complained yet!
