Choosing a screenwash for you car is a pretty easy task, right? Not always. There are some truly shocking screenwashes out there that do a poor job of cleaning your wind screen, as well as clogging up the washer nozzles. With that in mind, I’ve collated my favourite screenwashes below.
Autoglym Ultimate Screenwash
As is the case with their other products, Autoglym have made a really brilliant screenwash. It comes in a 500ml bottle of concentrate, but you can make up to 8 litres of product depending on how you mix it.
Autoglym do recommend that for extreme winters, you can use the product neat. That is for temperatures down to -45°C. Mind you, if it were that cold, I doubt that the car would function anyway.
In the winter, I use it at a dilution ratio of 1 part product to 4 parts water. In that case, I used 2 bottles of Ultimate Screenwash and 4 litres of deionised water. That was enough to make up 5 litres of screenwash in total so I’m always good to go in terms of topping up the washer bottle. In the winter where I live, it means that it won’t freeze. At that dilution ratio, Autoglym rate at as working down to -6°C. I had an unexpected cold snap and that went to -11°C and it still worked exceptionally well.
In terms of the cleaning power, it really is second to none. A little bit of screenwash on the windscreen goes a long way. Since the winter can be a pretty dirty time, it can be a worry for some drivers that their screenwash won’t be able to keep up with the road grime. This isn’t the case with Autoglym Ultimate Screenwash. It cuts through the dirt like a hot knife through butter, and it leaves a flawless, streak free finish on the glass.
I would always recommend using deionised water, which can push up the price a bit. However, I found that Asda sells 2.5litres of deionised Car Plan water for £1.25. This is a great price (just in case it’s not in stock on Amazon).
Whilst you need to make it up yourself, it offers great bang for the buck overall. It really doesn’t have much of a smell to it, which I’m fine with as well.
- Autoglym Ultimate Screenwash is a highly concentrated formula screenwash ideal for winter weather up to -45 degrees

Prestone Winter Screenwash
Despite the name, this screenwash can be used all year round. It is premixed, so it’s the simple case of pouring it straight into your washer bottle. Prestone claim that it works down to -10°C. I haven’t experienced temperatures that low. However, when I used it before at -4°C, it worked well.
Having said that, it does leave a clean windscreen, so it’s a big plus point safety wise. Much like the Autoglym variant, it doesn’t leave any streaks on the glass. In terms of cleaning ability though, Autoglym has the edge in this regard.
However, what I didn’t like was the smell from it. It’s a bit of a strange smell, not horrific, but not the most pleasant either.
The thing with the Prestone winter screenwash is that it still performed well, and works out cheaper per 5 litres than the Autoglym Ultimate Screenwash. If it’s the case that you don’t have the time to make up the screenwash yourself then this is a really good option.
- Thats why Prestone has developed products to keep you driving all year round.
