Your windshield washers are intended to help clean your windshield. Over time, this cleaning agent will also need to be cleaned itself. Windshield washers are exposed to various elements so it can get clogged or blocked by grime and dust. When it gets blocked, the fluid won’t be ejected properly, and the nozzle will lose its functionality.
Take note that wiper fluids don’t usually get blocked on its own. Only when dust and outdoor dirt gets into the hose and nozzles that it will start to malfunction. Here’s what you need to know about cleaning your windshield washers:
Step 1. Check the nozzle
Before you do anything, check the nozzles first and give it a gentle wipe. This will remove the external dirt. Usually, this will be mounted on the trunk or close to the windshield. In some car models, the nozzles itself are attached to the wiper blades.
Any large debris on the outer layer should be removed gently to prevent it from pushing into the nozzle opening.
Step 2. Use compressed air to clean the nozzle
Using compressed air (you can purchase this from most home supplies stores), blow the debris away. This stream of condensed air will unclog the nozzle opening and hose.
Aside from that, you can use an old toothbrush to remove the muck on the nozzle. If you haven’t cleaned your washer nozzles for long, it would have accumulated deep-seated grime.
Step 3. Unclog the hoses
If there are clogs on the fluid hose, you can use the same compressed air to blow it into out. You can detach the hose from the nozzle and reservoir to clean it easily.
Take note that removing the hoses will require more cleaning time. It’s not ideal to do if you’re in a hurry. You should use a pair of needle-nose pliers to detach the hoses from the coupling
Wipe the hoses and let the fluids drip into the reservoir. If the reservoir has dirt or muck, empty it and make sure that any possible blockage is gone before refilling it with a cleaning fluid.
Step 4. Take a look at the check valve
Depending on the setup of the washer, some will come with a check valve. If yours have one, make sure that you rule out possible leaks and backflow. Take note that even the check valve can be clogged as well. Compressed air will come handy here.
Step 5. Examine for other issues
After cleaning and putting back the washer system, you should also check for other problems. First, check the washer and ensure that it’s not blocked and working correctly.
Also, take the time to check the condition of your windshield wiper. If the rubber parts are worn out or falling off, it’s best to replace the blades with new ones.
Your windshield wipers are useful, especially if you’re hitting the road. Make sure that it’s always functional and reliable whenever you need it. A simple cleaning routine should extend its lifespan and reduce the cost of professional repairs.
