5. Auto Glym Ultimate Screenwash (500ml)

£8.99 (£17.98/litre) (Halfords)

Minimum temperature: -45C

4/5

The most costly possibility right here, and whereas Auto Glym’s screenwash can be essentially the most closely concentrated, diluting it right down to -6C energy ends in 2.5 litres of washer fluid – which is about the identical as you’d get from 1.25 litres of our different rivals in concentrated kind. So even with its low minimal temperature, that is an costly purchase, and whereas it cleans effectively, it isn’t noticeably higher than the remainder. That mentioned, when you pour it in neat you get the most effective chilly temperature safety – although after all, you’ll have to make use of honest quantity of it, for which your pockets received’t thanks.

6. TripleQX All Seasons Concentrated Screenwash (5l)

£5.29 (£1.06/litre) (Euro Car Parts)

Minimum temperature: unknown

3/5

At simply £5.29 for an enormous bottle like this, the TripleQX screenwash is the second most inexpensive fluid right here, which can tempt many consumers. Trouble is, it doesn’t clear brilliantly; what’s extra, there’s no guideline given as to the safety it provides towards freezing temperatures, so it’s a must to pour it in and hope. Indeed, the instruction to ‘pour directly into screen wash bottle’ makes you suppose it needs to be used neat – so is it actually a focus (somewhat than a ready-to-use answer) in any respect?
