Ice can form on the windshield washer lines in the winter, preventing them from working correctly. We will also cover some of the potential causes of this issue and prevent it from happening in the future. Read on for tips!

10 Ways on How to Thaw Windshield Washer Lines

1. Run Hot Water

Run hot water over the frozen lines for about 15-20 minutes. This works because the water that runs through your car is hot. It may take longer to thaw out if you have an older model. You can also try running very warm or hot tap water if you don’t have access to a hose.

2. Blow Dryer

If you have a small/portable blow dryer, put the hot air on low and hot settings. This should work almost as well as the water method. Try using a hairdryer instead of hot air from a clothes dryer if you don’t.

3. Heat Tape

You can also use heat tape to thaw windshield washer lines. If your owner’s manual says that you have the option of adding heat tapes, then this is an excellent option for you!

4. WD-40

WD-40 is a lubricant you can use to help your windshield washer lines thaw out. Spray it on the frozen line and the connecting ends, and let it sit for about four hours or overnight before trying to run water through them again. You may also need to spray some on the outside of the frozen line to make sure it’s not just a tube that has been damaged.

5. Dryer Sheets

Dryer sheets are antistatic, which can help pull water molecules from surfaces. While this doesn’t work as well as hot running water or a blow dryer, it still works. Rub a dryer sheet against your windshield washer lines and let it sit for several hours or overnight before trying to run water through them again.

6. Try Anti-icer Fluid

Anti-icer is a de-icing fluid for cars, and it has the same properties as windshield washer fluid. Put anti-icer fluid in your tank and let the car run to push the fluid through, which should help free up any water that’s frozen inside of your lines.

7. Soak line

Soaking the frozen line in a cup of warm water for five minutes (or however long it takes to thaw) should work as well. You can also try adding ammonia or vinegar if you don’t have any other options, but they may not work as well and could damage your car.

8. Try Hot Oil

If you’re willing to risk it, you could also try putting a small amount of hot oil on the frozen line. This will help thaw it out but could damage your car.

9. Select the Correct Fluid

Ensure that whatever you put in your windshield washer tank is the correct fluid for your car. This means it should be either washer fluid or anti-icer fluid, not any other types of fluids like shampoo, soap, etc.

10. Try Different Washer Fluid

If none of these methods work for you, you could always find a different washer fluid. Also, some brands perform better than others in cold weather, so maybe trying one that’s made for cold weather will help thaw your windshield washer lines faster.

Some Tips and Suggestions

1. If possible, remove the washer lines from under your hood and run the fluid through it. Then, just cut off a small section and re-attach them with hose clamps or electrical tape once they are functional.

2. If you cannot take out the washer lines, just let the engine warm-up for 30 minutes before trying to use them.

Washer Fluid Is Used in Freezing Temperature

3. If you still cannot get them to work, attach a garden hose or 5-gallon bucket to the washer nozzle and let it run.

4. Drive through an automatic car wash (not one that uses rollers) and spray off your windshield with the high-pressure washers at the end before jumping in line for the vacuum area.

5. If you have windshield wipers, turn them on before using the washer lines. This will help reduce the amount of water that runs down your windshield while trying to clean it with the normal washer system.

6. If that still does not work, check the reservoir in your car to ensure that there is windshield washer fluid in it. If there isn’t, fill it up and try again.

7. Drive to a nearby gas station with an outside spigot on the side of their building and fill your washer reservoir up from theirs before you leave. They will appreciate this as well since they can sell you more fluid if you run out.

Does Summer Washer Fluid Freeze?

As the temperature drops, your windshield washer fluid can freeze. If you live in an area that has cold weather for most of the winter, then you probably know that it’s possible to have a windshield washer fluid container that freezes upon you even if it is only filled with water.

Not only is this frustrating, but it can also affect the way your windshield is cleaned. Some research shows that when washer fluid freezes, it actually becomes cleaner, which is good for the environment but not for your windshield.

What Makes Washer Fluid Freeze?

Washer fluid freezes because the ethylene glycol has a freezing point of 26 degrees Fahrenheit (-3 Celsius). Washer fluid is used in freezing temperatures because the alcohol added increases the freezing point. This allows for greater viscosity (thickness) of the fluid, which helps protect your car’s windshield from freezing over when you’re driving.

Some windshield washer fluid also contains a blue dye, which helps protect your exterior car parts from UV deterioration. If the washer fluid turns cloudy or milky, that means that it has been diluted with water and can freeze as well. The more often you use it in freezing weather, the greater the chance that it will start to freeze.

How To Keep Windshield Washer Fluid From Freezing?

Windshield washer fluid is a key part of keeping your windshield clean, especially during the winter months. Windshield washer fluid is designed to be used when the temperature is above 0 degrees Celsius, but it can freeze in cold temperatures. This means that when you turn on your windshield wipers during a cold winter night, they may not function properly.

The fluid will be too thick, and the blades cannot swing properly. This can be dangerous because it could lead to a crash if you try to drive through a snowstorm. However, if you only need your windshield washer fluid for cleaning, then there is no reason why you should not just buy more of it during the summer months and keep it in your car just for this purpose.

Conclusion

If you want to avoid the cost and hassle of a windshield-washer fluid refill, follow these simple steps for how to thaw windshield washer lines. The most common cause of frozen windshield washer lines is a leaking head. When this happens, the water and wiper fluid can spill onto the ice below and freeze overnight, causing them to become solid in the morning when you go out to clear your car windows. 

To thaw it out, find some warm towels or clothing (if you forget) and wrap up either end of the hose with these items for about an hour before going outside. This should be enough time for them to melt through any frost on their way back into liquid form so that they will flow again when activated by your wipers!
