Can I use water instead of windshield wiper fluid?

As we mentioned earlier, the windshield wiper fluid is designed from a specific formula. It is designed precisely to do the job effectively without causing any issues and without dealing with extreme temperatures issues.

However, can water be a good replacement for windshield wiper fluid? Well, the short answer is no. There are many things to consider if using water instead of the windshield wiper fluid:

1.    Water is not as effective as the windshield wiper fluid

The windshield wiper fluid contains specific chemicals to clean the windshield in no time and just a couple of wipes. However, if you only rely on water, it wouldn't do the job, and there will be a lot of residual and contaminants on the windshield, making your visibility harder.

2.    Using only water might impact your safety

If you only rely on water and this water does not do the job by cleaning the windshield, you will impact your safety and easily get into dangerous situations without paying attention. This becomes extremely dangerous if you drive in foggy areas or contain a lot of dust in the air.

3.    Water does not support extreme temperatures

One of the most important benefits of using windshield wiper fluid instead of water is dealing with extreme temperatures. As you already know, water has a freezing and boiling point, which means that if the water is extremely hot or extremely cold outside, the windshield wiper fluid might not work as effectively as you're looking for.

For example, if the temperature outside is very hot, there is a high chance that this water might evaporate immediately after you spray it on the windshield. Similarly, if you use only water during very cold temperatures, there is a very high chance that this water might freeze in the reservoir or the pathways.

4.    Water might damage the internal reservoir and connections

Since we mentioned that water has a huge limitation When dealing with temperature if water flows are inside the connections. Inside the reservoir, you will deal with a more complicated problem where water might shrink or expand, causing cracks and other damage to the connections.

Of course, fixing these connection damages can be pricey, and it's way beyond what you're going to pay for using windshield wiper fluid or having a spare bottle in your vehicle for cases of emergencies. Therefore, you should think twice before using water instead of windshield wiper fluid.
