What to Do When the Wiper Doesn't Clean Properly?

Solutions for wipers not cleaning properly: You can wet the glass with water and run your hand over the glass back and forth. If the glass surface feels uneven, it indicates the presence of foreign matter. To remove it, wipe the glass with warm water several times, then use newspaper to clean off the dirt. Wipers, also known as windshield wipers or windscreen wipers, are devices used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. When it rains, turning on the wipers can clear the mist on the windows. However, you might notice that the wipers only remove part of the mist, and after wiping, the windows still appear very blurry, not achieving a particularly good effect. This is actually because the car has been used for too long, resulting in a layer of oil film adhering to the front glass, which is invisible to the naked eye. If there is an oil film on the car's windshield, even after using the wipers, the windshield may not be cleaned thoroughly.

After driving for so many years, nothing annoys me more than wipers that don't clean properly. First, thoroughly wash the windshield with a mixture of kitchen detergent and water, scrubbing hard with a sponge—pay extra attention to areas with heavy oil film. Check if the wiper rubber is cracked; if the edges are curled up, replace them immediately—don't wait until it rains to panic. Also, lift the wiper arm to check—if the spring is rusty and lacks tension, it won't clean well either—spray some rust remover. Always remember to turn off the wipers before shutting off the engine, as the rubber is more prone to deformation when exposed to sunlight. Last month, I followed these steps, and now even in heavy rain, my visibility is crystal clear.

Wipers not cleaning properly? Here's a money-saving trick! First, use an abrasive glass cleaner to wipe the windshield—this white paste is super effective against oil films. Then, check the wiper rubber. Flip it over and inspect the contact surface with your fingers. If you find fine cracks or hardening, replace it with a new one; aftermarket rubber strips cost just twenty bucks. Another secret tip: take a piece of 2000-grit sandpaper, wet it, and gently sand the hardened edges of the rubber strip to restore its elasticity immediately. But be careful not to over-sand, or it’ll be completely ruined. A mechanic taught me this during my last car service, and it worked flawlessly for three months in my car.

Three steps to solve wiper skipping: First, immediately stop and check if the wiper blades are stuck with leaves or sand particles; Second, open the hood and move the wiper arm to test if the rebound force is even; Third, start the vehicle, spray washer fluid, and wipe five times to observe the fan-shaped water marks. If there are blank areas in the middle, it means the blade is deformed and needs replacement. If streaks appear, clean the glass oil film. If your vision is blurry at night, deal with it immediately. Do not believe online remedies like using toothpaste to repair the blades—safety comes first.

From a mechanical perspective as an auto mechanic: The most common cause of poor wiping is an imbalance in the wiper arm pressure value. Use a spring scale to hook onto the middle section of the wiper arm for testing—the standard value for sedans should be 40-60 newtons. Wear on the connecting ball joint can cause the wiper blade angle to deviate by more than 3 degrees, manifesting as skipping on one side. When modifying, pay attention to the cutting angle of the rubber blade, with the factory 60-degree angle being optimal. Additionally, insufficient lubrication on the wiper motor gears can cause regular stuttering, resulting in water streaks at specific positions. It's recommended to perform a systematic adjustment before summer each year, which costs 70% less than replacing the entire assembly.

Girl, you see the wipers are like erasers, they get dirty after long use. Use wet wipes to clean the black rubber edges and remove embedded tar particles. For tree sap, use alcohol wipes on the windshield—those yellowish spots will shine right off. Lift the wipers and gently flick them a few times to listen for any squeaky sounds in the joints. If parked under trees, use a sunshade to prevent resin from hardening on the rubber. Last time when I drove my daughter to school in heavy rain, I noticed rainbow halos after wiping—that meant the oil film was too thick. It was only fixed by polishing with a dedicated compound in circular motions. Remember, safety is no small matter.
