Summer and winter windscreen cleaners – do not mix
A question on the subject of windscreen cleaners we are frequently being asked now is: “Can you actually mix a summer cleaner with a winter one?” Our Expert will has the right tip ready for you:
“When changing from summer to winter mode, the windscreen washer reservoir should first be sprayed as empty as possible. The reason for this is, the water contained in the windscreen wiper system reduces the freeze protection of the winter product, and the higher the remaining quantity of summer product, the greater the reduction.
Our Recommendation is: The new SONAX Antifreeze & clear view BLUE ENERGY with its energetic fragrance makes a pleasant change from the usual winter windscreen cleaner lemon scent. The modern product with its handy round bottle can be poured from all positions. As a ready to use mixture, in an optimum dosage with softened water, it provides clear vision even faster. The windscreen wipers will then require a minimal number of strokes, and that reduces consumption of cleaning fluid. Caution is advised with cheap products: Not only do they often function badly, they can also cause stress cracking in plastic headlight lenses. The consumption of cleaner is also above average high, which will very quickly cancel out the supposed saving.
Another tip: we regard the freeze protection data, claimed by several products as “to -60°C, as misleading: first, because in our latitudes temperatures of -20°C are rather seldom. And second,
in order to attain such unnecessary freeze protection, the product has to be used undiluted. The low water content leads to a poor cleaning result, particularly with the typical salt film. That is why the product’s cleaning performance is more important than the highest possible freeze protection. This is mixed by the manufacturer with water into a specific and optimum mixture and, it is ready to use in the area of application in which the salt film impairs visibility most – with temperatures around freezing point to a maximum of -20°C.”
