How do you unclog a spray nozzle on a windshield?

Having a clogged spray nozzle on your windshield can be incredibly frustrating. When you turn on your wipers in hopes of clearing away dirt or rain, you expect a helpful stream of wiper fluid to aid the process. But when the nozzle is clogged, you might end up with just a trickle, or even nothing at all. The good news is that unclogging a clogged windshield spray nozzle is usually a quick and easy process. Here’s what you need to know.

What causes clogged nozzles?

There are a few common culprits when it comes to clogged windshield spray nozzles:

• Dirt, debris, and environmental contaminants – Bugs, dirt, leaves, pollution, and other debris on the road can easily get stuck in the nozzle opening.
• Dried wiper fluid – The most common cause of clogged nozzles is old, dried fluid sticking to or blocking the opening.
• Mineral deposits – Minerals in tap water used to refill wiper fluid can leave behind mineral deposits that accumulate over time.
• Paint overspray – If the nozzle opening gets coated with specks of paint during auto body work, it can block the flow.

How to unclog a windshield spray nozzle

Unclogging a windshield spray nozzle is usually a quick fix. Here are some simple steps to try:

Step 1: Clean the outside of the nozzle

Carefully inspect the outside of the clogged nozzle. Use a small brush or toothpick to gently clear away any debris, dirt or dried fluid stuck to the nozzle opening. Be very gentle, as the plastic nozzles can be prone to damage. This step alone is enough to unclog many nozzles.

Step 2: Flush with warm water

If there’s still a clog after cleaning the outside, try flushing the nozzle with warm water. You can use a small syringe, turkey baster, or garden sprayer to aim a stream of warm water directly into the nozzle opening. The warm water can help dissolve any stubborn deposits or fluid.

Step 3: Use air pressure

For extra stubborn clogs, use compressed air to forcefully blow out the blockage. Canned air products work well. Hold the straw a few inches from the nozzle opening and give a few short bursts until you see fluid flowing freely.

Step 4: Use a needle or pin

If none of the above techniques work, very carefully insert a small needle or pin into the nozzle opening to loosen the clog. Be extremely gentle and stop immediately if you meet too much resistance to avoid damaging the nozzle. Use a back and forth or twisting motion to dislodge the clog.

Step 5: Remove nozzle for deep cleaning

For the most severe clogs, remove the nozzle from the wiper assembly altogether. This allows you to thoroughly flush, clean and inspect the nozzle and the feed line for any stuck debris. Reinstall once fully cleared of clogs.

Preventing clogged nozzles

A bit of preventive maintenance goes a long way towards keeping your windshield spray nozzles working properly. Here are some tips:

• Check nozzles frequently and clean as soon as you notice reduced spray.
• Rinse nozzles with water during routine car washes.
• Don’t “top off” wiper fluid without changing it – use fresh fluid mixes.
• Avoid tapping fluid that could leave mineral deposits.
• Trim overhanging trees to reduce sap and leaves hitting the windshield.

When to seek help

While most clogged spray nozzles can be unclogged at home, seek help from a professional if:

• You can’t unclog the nozzle after trying several methods.
• The wiper or nozzle assembly is damaged.
• Clogs reoccur soon after cleaning.
• You have reduced spray from several nozzles at once.

An auto technician has specialized tools to thoroughly clean the wiper fluid delivery system and diagnose any underlying issues causing repeat clogs or malfunctions. Expect to pay $50-$100 or more for professional windshield nozzle cleaning and repairs.

FAQs about clogged windshield spray nozzles

What if my car has two nozzles and only one is clogged?

It’s common for cars to have two nozzles, one on the driver’s side and one on the passenger’s. If just one nozzle is clogged, focus your cleaning efforts on that specific nozzle only.

Can I use vinegar to unclog my nozzle?

Yes, you can use a 50/50 mixture of vinegar and warm water to help dissolve and flush out debris in a clogged nozzle. The mild acidity of vinegar can help break down mineral deposits.

Why does my nozzle keep getting clogged?

Frequent clogs usually indicate an underlying problem, like a crimped fluid delivery line, broken pump, or contaminants in the wiper fluid. A technician can diagnose and fix the root cause of recurring clogged nozzles.

Do clogged nozzles cause any damage?

No, a clogged nozzle won’t directly damage your wiper system. However, lacking spray to clean your windshield can lead to reduced visibility and safety issues when driving.

Can I just replace the nozzle instead?

You can easily replace the nozzle instead of unclogging it. However, this isn’t necessary in most cases. Replacement nozzles are inexpensive though, typically $3-$8.

Conclusion

Troubleshooting a clogged windshield spray nozzle is usually a quick and straightforward process. In most cases, using a combination of flushing, air pressure, and mechanical cleaning will clear out the blockage. Preventing clogs comes down to keeping the nozzles clean and using fresh wiper fluid only. Persistent clogs may require professional help to identify and repair any underlying issues causing the problem.
