In winter, a good windshield antifreeze is almost indispensable for every driver, as it ensures clear vision even in the coldest weather and slushiest conditions.

In addition, good windshield antifreeze prevents the windshield wipers, which are already under greater strain in winter, from wearing out too quickly.

But what should you look for when buying suitable windshield wiper water for the winter?

Antifreeze for the windshield washer system: A test can reveal differences

In a practical test, the windshield washer fluid must of course be able to withstand the low temperatures in winter. Some antifreeze only provides reliable protection down to – 4° F Depending on the region and time of day, however, such temperatures are quickly reached in winter (especially at night or in the early hours of the morning on the way to work), so such minimal antifreeze protection can also fail a test report.

Anyone who wants to buy a particularly good antifreeze for the windshield washer system should therefore pay particular attention to the temperature resistance. One or the other wiper water with antifreeze should prove in the test that it can withstand temperatures from – 22 ° F to – 76 °F.

Which windshield antifreeze is right for your car

Buy windshield antifreeze cheap? This is neither difficult nor does it have to be accompanied by restrictions in quality – if a few points are observed. In a test, for example, you should compare antifreeze for the windshield washer system both as a concentrate or as a ready mix. Windscreen antifreeze concentrate is particularly favorable because it is diluted and thus lasts much longer. Indeed, the quantities in the canisters are usually specified as 3 or 5 liters, but often do not cost much more than a ready mix.

This is therefore proportionally more expensive but has the advantage that it does not need to be mixed with water and can thus be used directly. From the effect, the two do not differ, so that it is ultimately both a question of wallet and convenience, which variant is taken.

Do you want to buy a windshield antifreeze with an anti-lime effect?

Anyone who wants to buy windshield wiper water for the winter does not always necessarily think about the quality of their own water. If this is particularly calcareous, the nozzles can quickly become clogged.

When buying a windshield antifreeze, you should pay attention to the following:

  • a cheap windshield antifreeze can perform just as well in a test as an expensive product;
  • the anti-lime effect can be important depending on the water used for dilution;
  • a good windshield antifreeze should be able to withstand very icy temperatures of up to -76 °F, depending on the region in the practical test.

FAQ: Windscreen antifreeze

  • What does a windshield antifreeze do?

A windshield antifreeze ensures clear visibility in cold and snowy conditions and counteracts the rapid wear of the windshield wipers.

  • What should I look for when buying a windshield antifreeze?

When buying a windshield antifreeze, pay attention to the quality or hardness of your own water, temperature resistance and price.
