With the microfibers of this polishing cloth, you will properly clean the digital screens in your car. Since this Volvo-designed cloth is made of polyester, it is very suitable for delicate surfaces.

First, use the coarse side of the cloth to remove dirt and then use the other side to make the screen shine.

Microfiber is a durable material, giving the product a long life.
