What are the solutions for wipers not cleaning properly?

The solutions for wipers not cleaning properly are as follows: 1. Wet the glass with water and run your hand over it. If the surface feels uneven, it indicates the presence of foreign substances. To remove them, wipe the glass with warm water several times, then use newspaper to clean off the dirt. 2. You can sand the rubber strip on the wiper blade. It's important to note that you should not apply too much force when sanding the rubber strip. After sanding, the rubber strip will regain its effectiveness as when it was new. At this point, when you use the wiper again, you will find that it can clean the water mist on the windshield very effectively. 3. If the car has been used for a long time, a layer of oil film may form on the front windshield, which needs to be cleaned promptly.
I've encountered the issue of wipers not cleaning properly many times, usually due to aged wiper rubber strips or oil film on the windshield. Over time, the rubber strips harden and crack, losing their grip on the glass, resulting in blurred vision with water streaks during rain. This situation is easily resolved by replacing the rubber strips yourself – just purchase a set online for a few dozen yuan, making sure to select the correct size for your car model. Oil contamination on the windshield can also cause wipers to slip, especially after highway driving when insect remains and tree sap stick to the glass. You can use a specialized oil film remover for spraying and wiping, or apply toothpaste to a damp cloth and scrub the windshield vigorously for effective oil removal. Don’t forget to check if the wiper arm spring has sufficient tension, as insufficient tension prevents the rubber strip from adhering tightly to the glass. Before replacing the rubber strips, remember to clean the windshield and wiper bracket with a damp cloth to remove dust and sand particles, preventing premature wear of the new strips.
I've noticed that most of the time when wiper blades don't clean properly during daily driving, it's due to inadequate maintenance. The rubber strips usually age and crack in about six months, so it's recommended to replace them before cold weather sets in rather than discovering the problem during rain. Glass oil film can be prevented regularly - just use degreasing windshield washer fluid to wipe the front windshield during car washes. Try to avoid parking under trees or near kitchen exhaust vents to minimize resin and oil residue buildup. Once, my wipers were jumping because the wiper arm screw was loose; tightening it restored proper adhesion and fixed the issue. If new rubber strips aren't cleaning well, there might be fine sand or scratches on the glass - gently wipe with a microfiber cloth dampened with water. Never scrape the glass directly with hard objects, and avoid dry-wiping the wipers; spraying some washer fluid before activating them can extend the rubber strips' lifespan.
If the wipers aren't cleaning properly, try cleaning the glass first. Excessive oil film on the windshield can cause wiper skipping - use vinegar-soaked paper towels to wipe and the film will dissolve quickly. Replace worn rubber inserts by lifting the wiper arm and gently pressing the clips to remove old ones. Loose wiper brackets may cause shaking - simply tighten the connecting screws. Don't ignore washer nozzle alignment; misdirected spray causes uneven fluid distribution and makes wiping difficult. Remove any small leaves stuck in the rubber grooves. Avoid parking in direct sunlight during hot weather as heat accelerates rubber hardening.
