There’s no cheaper way we could find of making screenwash than this, except maybe putting a squirt of Fairy Liquid in the reservoir. But as with most things, you get what you pay for and the tablets seemed to do little more than colour the 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.

At the summer mix ratio the cleaning performance was adequate, clearing the oil and leaving a small residue of glue, but no smearing.It certainly seems to make financial sense if you do. There are usually two types on offer; ready mix or the concentrate. We tried both, but the results were almost identical so we’ve concentrated on the concentrate. We tried it at the suggested level for protection down to -22C and it was fine and fluid after several hours in the freezer, but at that mix ratio it would make little more than half a litre. 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. We tried seven different types, testing them for freeze resistance in winter conditions and cleaning ability at weaker summer concentrations.

As well as testing and our experience of using multiple screen washes, we also based our recommendations on the latest research and a number of factors. Some of the factors that we took into consideration included the formula’s type, seasonal use, freezing point, effectiveness and value for money.

First we calculated the costs of each in their winter and summer mixes. For the former we chose coverage down to about -10C, where there was a choice of mixes. The results make it difficult to believe these tablets are much more than just dye, and to compound our frustration the liquid also seemed to stain our containers and give our hands a blue tinge. Verdict In summer this makes it seem good value compared to some ready-mix rivals, but the advantage disappears in winter.

In reality though, that headline figure of -70C is only if you use the Wynns neat, which is unlikely to be necessary in the UK.
