Winter screenwash???
Discussion
I have been using the Porsche branded screenwash so far (only had the Cayman for 3 months), but am worried that it does not appear to have any anti-freeze properties.
Knowing that if certain brands of screenwash are mixed that they turn into a thick gel, is there any recommended winter screenwash as I do not intend to mothball the car over the winter (just not drive it while there is frost/ice on the roads...)

Meths will certainly prevent freezing but it could be detremental to paintwork and window rubbers.
Yes if you used it neat, but in small quantities I doubt its an issue - it it will evaporate very quickly anyway. (Can't recall what the recommended dilution is but it doesn't need much of the stuff)
From previous posts, the official Porsche Orange one is probably this:

I've been using different brands of screenwash for 25+ years and never had any experience of it turning to gel.
Another myth?
Don't forget to top-up the blinker fluid reservoir at this time of the year.

Clearly you've been using the "wrong" washer fluid ! Definitely not a myth. Gel might be pushing it, but turning into something with higher viscosity which won't go through the pipes, pump and jets, definitely.
I NEVER mix washer fluids now, I got fed up with having to strip arch liners out to get at increasingly awkwardly placed washer bottles, washer jets that won't come out of scuttle panels and washer jets with pipework so securely attached you can't disconnect them to enable you to remove them
I had to add some screen wash whilst on holiday which was non Porsche, it definitely turned to gloop took a while to dilute down to proper screen wash. Not very good when you are travelling thro France at cyber speed collecting thier wild life on your screen . Have a good supply of the Porsche stuff as they keep giving me bottles at service time, that's a joke by the way as giving is not a accurate description.
If I run out, will completely drain the system and fill with ordinary screen wash

you can add anti-freee rather than meths but there was a thread on here last year (which i can't find) about one type of anti-freeze potentially being detrimental to the paintwork and another attracting every cat in the neighbourhood and being poisonous to them!
Definitly wouldn't add antifreeze 
The standard Porsche "cleaner" is no good in the winter. I had trouble with it last year. Best thing is to get out all you can then flush with clean water before filling with an "All Season" type which will not freeze in - conditions (check dilution ratio). The trouble with Porsches is that the screen jets are so effective it takes ages to run out!

Agree, last year my washers froze inside my garage, the headlight washers came out and flew in the air when defrosted. Do Porsche sell a winter cleaner that can mix with the summer one ? Gassing Station | Porsche General | Top of Page | What's New | My Stuff
