What kind of water should be added to the windshield wiper?

[BrooklynLee]

Dedicated windshield washer fluid should be added to the windshield wiper. The method for adding windshield washer fluid is as follows: 1. Pull the hood release lever to open the front hood; 2. Open the washer fluid reservoir cap; 3. While filling, observe the dipstick inside the reservoir and fill up to the marked line. Windshield washer fluid is made from deionized water and various environmentally friendly additives, providing properties such as dirt removal, antifreeze, antistatic, corrosion resistance, rapid snow and ice melting, anti-glare, and anti-fogging, thereby enhancing driving safety. The usage method of windshield washer fluid is as follows: 1. Spray the washer fluid onto the area to be cleaned and wipe with a soft cloth until the area is clear; 2. For heavy dirt, repeat the cleaning process and rinse with clean water before drying; 3. After dilution, it can be directly poured into the vehicle's windshield washer reservoir for on-the-go use; 4. For winter antifreeze and anti-fogging, it can be used in conjunction with automotive glass anti-fogging agents.

I've been driving for several years and know that the windshield washer reservoir shouldn't be filled with ordinary water. It's best to use dedicated windshield washer fluid. Plain water can freeze in cold weather, clogging the spray nozzles, and over time it leaves mineral deposits that damage wiper blades and the pump. Washer fluid contains antifreeze and cleaning agents, remaining fluid below freezing temperatures while effectively cleaning the windshield without scratching the glass. During each maintenance check, I inspect the reservoir and top it up with season-appropriate fluid - using cleaning-type in summer to remove insect stains and grease, and antifreeze-type in winter to prevent freezing. Don't overfill when pouring to avoid diluting the concentration. Never cut corners by using tap or mineral water, as they lack protective additives and may ultimately cost more in repairs. Maintaining this habit ensures consistently clear and safe driving visibility.

As an average driver, I once tried to save money by filling my windshield washer reservoir with plain tap water, only to encounter a host of issues: poor spray performance and strange noises from the nozzles. At the repair shop, the mechanic explained that impurities in regular water can clog the system and cause freezing in cold weather. He recommended using professional windshield washer fluid, which contains antifreeze components and cleaning agents to protect the system. After switching, I noticed an immediate improvement in spray consistency, better cleaning efficiency, and time saved. Since then, I always keep a bottle of washer fluid in my trunk and check/replenish it monthly. Don’t repeat my mistake of cutting corners—regular maintenance keeps your car running smoothly and avoids unexpected expenses.

I always use professional windshield washer fluid. Ordinary water can freeze in cold climates, making it impossible to spray; it also provides poor cleaning and leaves water stains. Windshield washer fluid prevents freezing and contamination, protecting the wiper system. Before adding fluid, check the reservoir to ensure it's clean; pour an appropriate amount suitable for the season. Avoid adding mineral water or tap water to prevent damage. This ensures safer driving.

Some people want to save money by adding distilled water, but windshield washer fluid is better as it contains additives for antifreeze and dirt prevention. I recommend purchasing commercial products with reasonable formulas that won't harm the vehicle. Empty the old fluid before adding new one, as mixing might cause reactions. For average users, choosing big brands is more worry-free. Change types seasonally: use cleaning formulas to remove stains in summer, and antifreeze formulas in winter. Simple maintenance helps extend wiper lifespan.
