Unparalleled winter protection: experience extreme performance during winter with the ability to use the concentrate neat, providing exceptional protection even in frigid temperatures as low as -23°c. The Halfords wash gave the best cleaning performance and excellent freeze resistance at a reasonable price so takes the win here, but we’d recommend buying the ready mix rather than the concentrate as – bizarrely – it’s better value.

There is little aroma, no foaming and the fluid turned to ice as soon as the temperature dipped below zero. In the cleaning test it left smears from the oil and had no more effect on the glue than plain water. Below is a video we posted on our YouTube channel that shows us testing one of the screen washes. As you can see, it takes less than a minute to top up the screen wash and the bottle on this particular screen wash had an “easy-pour” spout that made pouring in the formula far easier and less messy.

For reasons of hygiene and safety, personal grooming products, cosmetics or items of intimate clothing cannot be returned. However, there was some good news. As we didn’t need the full -20C protection we economised and tried a few different concentrations to see how they fared in the freezer. A mix of 50/50 with water was still squirting after 12 hours at -18C, so it would seem Halfords is understating its performance. The instructions recommend it is used at the ‘optimum clean’ dilution ratio of 1:9, which stops freezing down to a claimed -3 oC.

In fact, the instructions only suggest diluting it by up to a factor of 3:1, which means one bottle would only make a litre of fluid. Since the average washer reservoir is three to four litres, that’s going to be expensive.note】the screen wash tabs do not prevent the water in the tank from freezing. temperature requirements need to be above -5°c (23°f). when cold, it is best to mix with antifreeze. In summer, it makes up to 10 litres and give protection against freezing down to -2C. If you need to go any colder it’ll need to be used 1:1 or even neat. The instructions say this will remain fluid down to -10C, so unsurprisingly it was solid after a few hours in our freezer compartment.

The cleaning ability was adequate if not spectacular, clearing the oil but leaving a remnant of our glue. This means that the Tesco wash is good value, but you’ll need to use more of it to clean away screen grime and refill the reservoir more often. Prestone Max Visibility Screen Wash At a summer mix rate of 4:1 the Halfords wash cleared both the glue and the oil after a few wipes, giving the best cleaning performance in the test. Autoglym Ultimate Screenwash 500ml In summer this makes it seem good value compared to some ready-mix rivals, but the advantage disappears in winter.

Tesco Concentrated Screen Wash (& Tesco Ready To Use) The bottle of Wynns is the smallest here, yet it claims to be ‘Super Concentrated’ and offer protection down to -70C.
