Frost, salt residue and slush mean hard work for the windshield wiper system. Without a good cleaner, you quickly lose visibility, so you should refill before the spray nozzles run out. It doesn’t matter at all what you pour into the washer fluid tank.
The most convenient are ready-made mixtures, of which there are many convincing ones, as a test by “Auto Bild” shows. The best among them is “Anti-Frost & Clear View” from Sonax with a grade of 1.3. With just the fourth wiping cycle, the test winner gets the window completely clean, and he also achieved full marks for frost protection, which works down to minus 20 degrees. With a price equivalent to 55 cents per cleaning process, the Sonax product is also the cheapest in the test, which also makes it the price-performance winner. A total of six usable candidates. Five other products were also convincing and achieved grades between 1.9 and 2. 4: “Nigrin windscreen antifreeze Energizer ready mix”, “Cartechnic windscreen cleaner with antifreeze ready to use”, “Total Wash windscreen antifreeze ready mix”, “Caramba Winter windscreen cleaner ready to use” and “Robbyrob Klarblick Premium antifreeze”. Sonax was also the test winner among the concentrates , which the KÜS carried out last year: but it was also graded “poor” twice. Both “Klax windscreen antifreeze ready-mix” and “JMC windscreen cleaner with frost protection ready-mix” delivered poor cleaning performance. Different requirements for summer and winterWindow cleaner is available in a summer and a winter version. While the former contains, among other things, protein-dissolving additives to combat insect residue, alcohol is added as antifreeze in the cold season. In general, windshield cleaners are available as a ready-made mixture and as a concentrate. The latter are usually a little cheaper, but you have to measure and mix it yourself. It is important that the cleaner has a test seal. Unsuitable agents can attack paint and rubber seals or cause stress cracks in headlights. (SPX)
