The problem with the front windshield causes the wiper to make a strange noise and cannot be wiped clean

Firstly, there are several reasons for the unclean and abnormal noise. For example, there is oil film, gum, and shellac on it.

How to clean gum and shellac

Check for yourself. If there are many small bits of the same thing on the front bumper, it means it has been stained with gum or shellac.
Spray some glass water, then wipe it vigorously with a towel, and it's basically done. It's really not possible to get some alcohol and it will be quickly removed.

How to handle oil film

If there are colored reflections on the front bumper after the rain has been wiped, and the bumper is prone to sticking together before the rain, it is likely that there is an oil film.The best way to remove the oil film is to wash it once with an oil film cleaning agent. If not, use toothpaste to remove the oil film.

The wiper is damaged and the wiper makes a strange noise, but it cannot be wiped clean

The wiper has reached its lifespan and needs to be replaced

The second situation is that there is a problem with the wiper itself. The wiper lifespan is usually around 3 months to 6 months, and when the time comes, it needs to be replaced.

Simply put, the wiper is a snap on type. Just press and hold the small snap in the middle of the wiper interface, pull it out, and you can take it off. Finally, the new wiper card is completed.

But before changing, remember to put a towel on the glass. If you accidentally touched it, you turned around and hit the windshield with your hand, causing it to bounce back. Unfortunately, the front windshield was damaged.

It is also possible to only replace the adhesive strip

If you think it's not cost-effective to replace the wiper every time, you can just replace the wiper rubber strip.

Just remove the fixing clip of the wiper strip, remove the old strip, replace it with a new one, and finally clip in the clip.

Of course, you cannot just replace the rubber strip every time, because the wiper itself will deform after being used for a long time.

In the video, I saw that the old windshield wiper is obviously a bit straighter than the new one, causing it to not fit the front gear better, so it straightened and cannot be wiped clean.

We'd better replace the rubber strip once and then directly replace the entire wiper, which is relatively cost-effective.

It is not recommended to use sandpaper to polish the wipers

Some people say that the wiper strip is old, and if you use sandpaper to polish it and continue using it, it will save even more money.

This is not particularly recommended because the adhesive strip itself contains lubricants such as graphite.

The sandpaper has been ground down, but it can't be scraped clean and there is a strange noise. If it doesn't work properly, what should we do if we scrape the glass.

The wiper arm is damaged, causing the wiper to make a strange noise and cannot be wiped clean

If the wiper is replaced and the oil film is also removed, there is still a problem of not being able to clean and making abnormal noises. It is possible that there is a problem with the wiper arm.

The wiper arm spring is rusted and deformed, causing it to not be wiped clean

Because the wiper arm has been used for a long time, the springs inside it rust, and irreversible deformation can also produce abnormal noise, which also causes the wiper to not fit properly and not clean.

The wiper spring can be replaced separately, but the difficulty is a bit high, so I don't recommend it very much.

If the spring is rusted, the interface at the root of the wiper arm may also be rusted, and replacing the spring alone won't make much sense. You might as well replace it together.

How to replace the wiper arm

So first remove the wiper and then unscrew the fixing screws of the wiper arm.

The fixing screw is usually located at the root of the wiper arm, and there will be a circular small cover covering it. There is a small groove under the small cover, and the screwdriver can be inserted to pry it open.

After unscrewing the fixing screws, you cannot directly remove the wiper arm. You need to fold the wiper arm in half towards the middle first to obtain it.

When installing the wiper arm, maintain the same angle as the old wiper arm, so before removing the wiper arm, remember to make a small mark with the small groove on it, so that it is not easy to remember incorrectly.

So when taking down the old wiper arm, fold the new wiper arm in half towards the middle, then align the marks and install it. Remember to tighten the screws a bit. Finally, install the wiper back and it's done.

Suggest checking the wipers first

Actually, as long as you follow the steps in this video step by step, if you think it's a bit fast, you can pause for a moment, right. The problem of abnormal noise and poor cleaning of ordinary wipers can be solved.

If you really think there are too many steps, then it is recommended that you check the wipers first, because most friends' wipers make strange noises and cannot be wiped clean, which is caused by the wipers.

How to replace the wiper rubber strip

Some friends have questions. My wiper interface is different from the one in the video. How can I replace the U-shaped interface or universal interface?

Is there a different replacement method for the rain scraper adhesive strip, which has bones or no bones? Where can I buy it? How exactly should I change it?

On rainy days, besides the front bumper, I can't see clearly, and the rearview mirror is also unclear. What should I do? I have prepared all these materials for you, and I have also created the video for you. You can watch it step by step and handle it.
