When driving a car, many people notice that drivers often keep a bar of soap inside. So, what is the purpose of this bar of soap?

First of all, experienced drivers say that placing a bar of soap in the car is mainly because the vehicle is a relatively closed environment, which easily develops unpleasant odors, especially in the cold winter when warm air is blown inside. The air conditioning system often mixes with some indescribable smells.

Although many people like to put so-called air fresheners in their cars, their effect is not as good as soap. Moreover, a bar of soap is relatively inexpensive, and from time to time it can even be taken home and used for laundry after being kept in the car.

In addition, drivers point out that at critical times, soap can even play a life-saving role. For example, on a rainy day, raindrops falling on the windows will affect the driver’s visibility. While windshield wipers can solve this issue for the front and rear windows, they cannot deal with the side mirrors. However, rearview mirrors are especially important in rainy weather. At this time, you just need to rub soap onto the mirrors and wipe it clean with a tissue after a few minutes.

This works similarly to applying a protective film on the mirrors, so there is no need to worry about losing visibility in rainy or stormy weather.

Of course, drivers warn not to underestimate the role of soap. Not every car is equipped with heated mirrors. The configuration of budget cars certainly cannot be compared with luxury ones. But sometimes, more features do not always mean better, as even high-end systems can fail. Applying soap to the rearview mirrors will keep them clean, making it easier and safer to observe the road.

Finally, experienced drivers emphasize that soap should never be underestimated. It not only eliminates odors inside the car and freshens the air, but also helps ensure safer travel during rainy and windy days.
