Unfreezing Windshield Wiper Fluid
Windshield wiper fluid is essential for maintaining visibility while driving, especially during adverse weather conditions. However, in extremely cold temperatures, this fluid can freeze, rendering your wipers ineffective. Here’s a step-by-step guide to help you unfreeze your windshield wiper fluid.
Step 1: Move the Vehicle to a Warm Area
If possible, move your vehicle into a garage or another warm, enclosed area. Increased ambient temperatures will help thaw the wiper fluid more quickly. If you do not have access to a garage, you can skip to the next step.
Step 2: Apply External Heat
If you cannot move the vehicle to a warm area, you can apply external heat to the fluid reservoir and the wiper lines.
- Use a hairdryer: Direct a hairdryer on the warm setting towards the windshield washer reservoir and the lines leading to the wiper jets.
- Place warm compresses: Soak a cloth or a sponge in hot water, wring it out so it’s not dripping wet, and place it on the reservoir and along the lines.
Be careful not to use boiling water or an open flame as these can cause damage to your vehicle.
Step 3: Use a Windshield De-Icer Product
Purchase a commercial de-icer product and spray it onto the windshield and fluid nozzles. These products are formulated to lower the freezing point of the wiper fluid and can quickly unfreeze the solution.
Step 4: Add Concentrated Windshield Fluid
If your windshield fluid is still frozen, your current mixture may be too diluted for the temperatures you’re experiencing. Add a more concentrated windshield fluid which has a lower freezing point.
- Ensure the vehicle is in a safe place with ample ventilation.
- Open the wiper fluid reservoir and carefully add the concentrated fluid as directed on the bottle.
Step 5: Let the Engine Warm Up
Start the vehicle and let the engine warm up for some time. The heat from the engine can help raise the temperature under the hood and contribute to defrosting the wiper fluid. Do this for about 10 to 15 minutes.
Step 6: Try the Washer Jets
After applying heat, try using your washer jets occasionally to see if the fluid is coming out. If it is, use the windshield wipers to clear the fluid and ensure it’s spraying properly.
Step 7: Preventative Measures
To prevent wiper fluid from freezing in the future:
- Use a proper winter blend wiper fluid that is rated for low temperatures.
- Mix your own wiper fluid with a high concentration of isopropyl alcohol, which has a very low freezing point.
Please note: When unfreezing wiper fluid, never use hot water directly in the reservoir as it could crack the plastic when it contacts the frozen fluid. Always approach steps involving heat with caution to avoid any damage to your vehicle or injury to yourself.
Conclusion
Frozen wiper fluid can be an inconvenience, but with patience and careful application of heat, you can unfreeze it and be back to safe driving with clear visibility. Always ensure you have the correct wiper fluid mixture for your climate to minimize the chances of freezing.
