What are the causes of wiper blade noise?

The causes of wiper blade noise are: 1. Issues with the wiper blade itself, it is recommended to replace it promptly; 2. Foreign objects caught between the wiper blade and the windshield, ensure the wiper blade area is clean; 3. Noise caused by friction in the wiper linkage bushing, inspect the wiper arm or linkage bushing; 4. Abnormal noise from the wiper motor, it is advisable to conduct a detailed inspection at a professional repair shop. The wiper, also known as a windscreen wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. The wiper consists of components such as an electric motor, reducer, four-bar linkage mechanism, wiper arm spindle, and wiper blade assembly.
I've been driving for over a decade, and the squeaky wiper blade issue is really annoying. The most common cause is hardened rubber due to aging, especially for cars parked outdoors under prolonged sun exposure - the rubber surface becomes full of cracks. Oil film on the windshield can also cause skipping and squeaking, particularly noticeable for cars frequently parked under trees where tree sap mixes with grease. Loose wiper arm springs may result in insufficient pressure, creating a clicking sound during operation. There's one easily overlooked detail: when installing new wipers, improper angle adjustment may cause only half of the rubber to contact the glass. Remember to clean dust particles off the blades during each car wash, and check for ice buildup before starting in winter. Replacing blades before rainy season is the safest approach - it's literally a lifesaver.
