How to Clean a Clogged Mercedes Windshield Washer Nozzle?

On the left side of the driver's compartment, locate the vehicle's hood release switch and gently pull it upward. If the washer nozzle is clogged, you can use a sewing needle to insert into the nozzle hole and unclog it. Gently pry up the windshield washer nozzle on the hood that is not spraying. After unclogging, check the spray height. If the height is not appropriate, use the sewing needle to adjust the nozzle opening to ensure smooth water flow after unclogging. It is recommended to regularly add windshield washer fluid to prevent nozzle clogging. You can gently pry the nozzle multiple times to remove the windshield washer nozzle. Regularly check the nozzle for debris at calculated intervals to prevent future clogging.

I've been driving a Mercedes for many years and have also encountered clogged washer nozzles, usually due to solidified car wash soap or dust stuck in the holes. When cleaning, first try gently inserting a thin needle into the nozzle to unclog it, but don't use too much force to avoid damaging the parts. If that doesn't work, remove the nozzle—most Mercedes nozzles are easy to pry open—rinse them with water, let them dry, and then reinstall them. Prevention is more important in daily use. I insist on using high-quality windshield washer fluid instead of tap water to reduce clogs. If left untreated, clogged nozzles can lead to poorly cleaned windshields, affecting safe driving. This experience has saved me a lot of trouble, and I always remind my friends to check the nozzle condition before each car wash.

When encountering a clogged spray nozzle on a Mercedes, my usual approach involves several steps. First, activate the washer system to identify which nozzle isn't spraying. Second, use a fine needle to gently dislodge the blockage, avoiding sharp objects to prevent scratches. Third, if it remains clogged, remove the nozzle and use compressed air or clean water to flush it out. Finally, reinstall and test. For regular maintenance, I make sure to periodically clean accumulated dust near the wiper blades to prevent debris from entering. The spray nozzles on Mercedes vehicles are made of sensitive materials, and forcing washer fluid through them could damage the motor. After cleaning, ensure the water flow is even—safety first. This DIY method is simple and effective.

Clogged spray nozzles are a common issue in Mercedes-Benz vehicles. When cleaning them, I first use a soft brush or a pin to gently clear the holes. If that doesn't work, I remove the nozzle and soak it in warm water to dissolve the dirt. Be careful not to force anything during the process to avoid cracking, as Mercedes parts are quite precise. It's safer to seek professional maintenance. Regularly replacing the windshield washer fluid can reduce the risk of clogging, and developing this habit can extend the nozzle's lifespan.
