Surely you must mean Prestone!
The screenwash is great, use it undiluted to instantly cleat frost and snow.

The shampoo is not good, but hey, its cheap.
Usually buy the Halfords Pink stuff (works well, smells great), but thought I’d try from Costco instead - works well but smells awful, like vinegar. Can’t remember the brand but don’t think they do many.
Thanks @scottiebottie , this is very good screenwash, assuming it is Prestone and not some knock off brand called Pristone. Assuming it is Prestone I've edited the typo. Hope that's OK with you.
The screenwash has a rain repellent additive. When it is cold, your windscreen will have visible white haze. In direct sunlight you won't see anything at all. You basically have to wait for your engine to warm up before you set off.

The easiest way to get rid of that layer I found was to use a nylon brush and dish soap and water. Obviously don't use a rain repellent screenwash in the cold months afterwards.
Has anyone else used the blue Prestone concentrate screenwash? I usually buy autoglym screenwash which works well but obviously works out more expensive. Popping down to Costco on Monday anyway so might pick up one unless advised otherwise.

Didn't notice that when i used the ready to use one - yellow colour. I'll check tomorrow if mines the same. Can understand what you mean mind.

Maybe the ready to use has less of the rain repellent than the Costco one. A case of YMMV I guess
