Quite a lot of motorists in our time are faced with such a common problem as the problematic functioning of the windshield washing system. Because of this, wipers leave annoying streaks and streaks. As a result, the review may become even worse than before trying to wash the glass. Many in such a situation immediately run to change the cleaning brushes, but this approach often does not give the desired result.
The essence of the problem boils down to the fact that in fact, in most cases, stains on the glass remain not at all due to wear and tear on the wiper blades, but because they are incorrectly fixed. And this, in turn, means that changing the rubber bands themselves is a thankless and even empty business. To solve a problem of this kind, it is necessary to approach the solution from a fundamentally different angle.
Recall that the wiper blades are pressed against the car glass using a special spring, which closes with a special metal body to protect it from external influences. Despite the presence of a shield, over time, the spring becomes unusable, ceases to provide the proper force due to the fact that it is corny stretching. Accordingly, without the necessary effort, the correct cleaning of the windshield is out of the question.
