Screenwash

I always learn something new on this forum and today it was screen washer fluid - never knew it warranted discussion.

Maybe I should stop squirting in fairly liquid every time I top up the reservoir with water

I've done this at a pinch if i've needed to in the past, as others have said supermarket premixed fluid is perfectly fine, a 1 gallon jug will do about 2 top ups.

Be careful. I blocked my M3P scooshers by putting too concentrated fluid in. All sorted by Tesla Aberdeen at no cost (great service). The technician there recommended Tesco own brand pre mixed, so as to avoid gunking up the tubes. Key message is get it ready mixed so the concentrations are right.

I'm expecting my new M3LR this week, I plan to use a hybrid ceramic wax or similar straight away. As these types of coatings require a ph neutral car wash, should I use a ph neutral screenwash too? If so, can anyone recommend one?
Thanks in advance.

I favour blue as long as the bugs are pH neutral, too. Pigeon poo is a different problem.

Do they really require a pH neutral car wash? I’ve had all my cars ceramic coated and was never given this guidance, nor did it seem to make any difference how I washed it. I have started using a DI vessel to deionise the final wash, mainly because I’m lazy and it means I don’t have to chamois it.

CAUTION: Do not add formulated washer fluids that contain water repellent or bug wash. These fluids can cause streaking, smearing, and squeaking or other noises.

I've topped my washer fluid up with a couple of fluid ozs of this, and it's not provided any problems with smearing/streaking/juddering whatsoever. Or with the original RainX stuff that I treat the windscreen with when I clean it.

The hybrid ceramic stuff I've been recommended to use does say on the usage instructions to use a ph neutral car wash to avoid stripping the coating. So I thought maybe a harsh screenwash solution may do the same?

It would have been nice if you had quoted my whole post - I was referring to what is said in the manual.
