Identifying The Problem With Frozen Windshield Wiper Fluid

The first step in dealing with frozen windshield wiper fluid is figuring out what’s going on.
It’s like solving a mystery but with less drama and more ice.
Inspecting Your Windshield Washer Fluid Reservoir
Take a peek at your windshield washer fluid reservoir.
Look for cracks or leaks that could be letting in the cold. If you can’t see anything, use your detective skills and feel for wet spots.
If the reservoir is fine but your windscreen washer fluids systems are still acting up, it’s time to consider other factors.
Checking Whether Your Windshield Washer Pump Is Running
Now, let’s see if your windshield washer pump is doing its job.
Turn on your car and activate the washers.
If you hear a humming noise but no liquid comes out, something might be blocking the way.
Sometimes the nozzles get blocked with age and debris. A toothpick can clear up the holes pretty easily.
Next up would be the wiper fluid hoses.
These are thin hoses that connect from your washer fluid pump to your nozzles. These can also freeze over so tracing them back by feeling is your best bet.
If you feel hard obstructions or see tears. You’ve found the culprit.
If you’ve checked everything and still can’t solve the case of the missing spray, it’s time to take more drastic measures.
Thawing Out Frozen Windshield Wiper Fluid

In areas with freezing temperatures, dealing with frozen windshield wiper fluid can be a real pain in the glass.
But fear not, there are a couple of ways to thaw out that stubborn icy slush.
Hot Water to the Rescue
If your windshield washer fluid has turned into a popsicle, you can use hot water to bring it back to life.
Just be careful not to pour boiling water directly onto the reservoir, unless you want a cracked windshield (and not the good kind?).
Instead, grab a pitcher of hot tap water and slowly pour it over the frozen fluid. It might take a few pitchers, but eventually, that miraculous fluid will start melting away.
Blow It Away
Alternatively, you could try using a hairdryer on low to waft some warm air over the hoses, if you don’t want to use hot water. e
No, not with your mouth (that would be weird), but with a hairdryer or heat gun set on low.
Gently blow across the washer fluid hose sections to defrost any ice blockages.
Just remember to keep moving and not focus on one spot for too long, unless you want to give your hoses a hot makeover.
Cranking Up The Heat
If you’re fortunate to have a garage where you can park your car and don’t need to use your car for a while, let the heat rip.
Park your car, jack up the heat, or use a portable space heater. Let time do the work and eventually all frozen things will unfreeze. Just make sure all heaters and things are away from flammable objects.
We don’t want to cook your car after all.
Restoring Normal Functionality After Freezing Issues

Defrosting is only step one in fixing your frozen windshield wiper fluid system. We need to make sure it works as normal.
Otherwise, you’ll end up with streaky windshield wipers. If you happen to find yourself with that problem check out our guide on how to fix streaky wipers here.
The Power of Windshield Washer Concentrate
Enter windshield washer Concentrate, the superhero of windshield cleaners.
This stuff not only cleans your windshield like a boss, but it also protects against freezing. Mix some water with washer Concentrate and you’ll be ready to rock.
With a higher strength formula than standard washer fluid, Concentrate can tackle bugs, grime, bird droppings, and even tree sap.
No streaks, no residue – just a clear view for safe driving.
I recommend Meguiar’s Glass Cleaner Concentrate.
It works great as a stand-alone cleaner and can even be added to wiper fluid to make sure your windshield is always clean.
The aftermath of dealing with frozen windshield wiper fluid can be quite stressful.
However, it’s crucial to take preventive measures after such an ordeal to avoid future occurrences.
This is especially important during cold winters when these problems are most likely to happen again.
Maintaining Optimal Condition of the Washing System
To keep your car cool and ready for any weather, here are some tips to maintain the optimal condition of your windscreen washing system:
- Routinely Check Your Windshield Wipers: Regularly inspect your windshield wipers to ensure they’re in good working order. Replace them immediately if there’s any wear or damage.
- Clean Your Windshield Regularly: Keeping your windshield clean improves visibility and allows the washer fluid to evenly spray without obstruction.
- Avoid Using Water as Windshield Washer Fluid: In colder climates, water will freeze quickly, causing issues with your pump running slowly or not at all. It’s also not a good cleaner.
Additionally, check if the washer fluid hose sections are clogged up by frozen fluids from previous usage. This could prevent new liquid from reaching its destination effectively.
If you notice that despite taking all the precautions mentioned above, your windshield washer pump isn’t running properly, consider seeking professional help.
There might be more serious underlying issues that need addressing promptly before they escalate into bigger problems.
No one wants their morning commute interrupted by something as simple yet frustrating as a frozen windshield wiper fluid issue.
By taking care of our car’s windscreen washer fluid systems and implementing these preventive measures, we can ensure smoother drives during those icy cold winters while keeping our vehicles looking spick-and-span.

Can Rubbing Alcohol Unfreeze Windshield Wiper Fluid?
Yes, adding a small amount of rubbing alcohol to your washer reservoir can help prevent freezing.
Just be careful not to use too much, as it could damage your car’s paintwork.
Wrapping Things Up
By inspecting the reservoir and checking the pump, you can identify the problem.
Thawing methods such as using hot water or blowing warm air across hoses can help restore functionality.
For completely frozen reservoirs, placing them near heat sources or flushing with hot water before parking in garages can be effective solutions.
Additionally, products like Washer Concentrate and industrial strength cleaners can aid in restoring normal functionality.
