How can we clear the mist from the inside of the windscreen when it is raining?

Explanation
To eliminate the **fog from the inside of the windshield** in case of rain, it is important to use the **heating system directed at the front windshield**. This system helps to defog the front glass, improving visibility while driving.
- The **windshield wiper** is a device that keeps the front glass clean, but it does not eliminate fog. Its main function is to clean rainwater from the windshield.
- The **rear window defroster** is located on the rear glass and is designed to remove ice and vapors from that glass, not the front one. Therefore, directing the heating towards the rear window would not solve the fog problem on the front windshield.
- Opening the windows can help reduce fog, but it is not as effective or quick as using the heating system directed at the front windshield.
For these reasons, the best option to eliminate fog from the front windshield is to use the appropriate heating system.
