Is It Dangerous to Spray Floral Water in the Car?

Spraying floral water in the car can be somewhat dangerous, and it is generally recommended to dilute the floral water before spraying it in the car. 1. Floral water contains alcohol, and if sprayed directly in the car, it can easily ignite in high-temperature environments, potentially causing a fire, which is quite hazardous. 2. When using floral water to spray inside the car, it should first be diluted with water, placed in a spray bottle, and then sprayed inside the car. Be careful not to spray too much at once to avoid excessive concentration of floral water in the car. Below are the benefits of spraying floral water: 1. Odor removal and fragrance retention: In summer, the car often develops unpleasant odors or other smells. Spraying some floral water at this time can freshen the air inside the car. This is because floral water contains alcohol and fragrances; the alcohol evaporates and carries away some of the odors, while the fragrances produce a pleasant scent. 2. Insect repellent: During summer, the car may also have mosquitoes or other insects. Spraying an appropriate amount of floral water can effectively repel these insects, providing excellent insect-repellent effects.

My family likes to spray toilet water in the car to repel mosquitoes, but this is actually quite dangerous. Most toilet water contains alcohol, which can easily catch fire when exposed to high temperatures inside the car. Last summer, a car in our neighborhood caught fire because a bottle of toilet water was left under the windshield and exploded due to the sun's heat, igniting the interior. Moreover, spraying too much toilet water can make the car smell pungent, causing dizziness and nausea during long drives. Extra caution is needed when traveling with children, as their delicate skin may have allergic reactions if toilet water is sprayed directly on the seats. For mosquito prevention, it's safer to use solid mosquito repellent balms or patches.

Over the years as an auto repair technician, I've witnessed numerous cases of car fires, and floral water (huā lù shuǐ) is indeed a potential hazard. With alcohol content typically exceeding 70% and a low flash point, summer cabin temperatures can easily reach 60-70°C. Once, a customer left floral water on the rear windshield parcel shelf—direct sunlight caused the bottle to rupture, and the liquid dripped onto seat heating wires, immediately producing smoke. Additionally, spraying floral water on leather steering wheels or dashboard panels accelerates material degradation, and repairing these areas is particularly troublesome. If you must use it, spray it into the air vent fragrance diffuser slot, keeping it away from wiring clusters at minimum.

Just saw a news report about a vehicle spontaneously combusting in a certain area, with the investigation revealing that it was caused by toilet water. The main components of this stuff are ethanol and menthol, which are volatile at room temperature. In an enclosed car space, spraying too much can accumulate high concentrations of alcohol vapor, which becomes dangerous when encountering sparks from a cigarette lighter or aging wiring. Last time, my husband tried to light a cigarette with a lighter, and suddenly a blue spark flashed, scaring him into immediately opening the windows for ventilation. Later, after checking some information, we learned that an alcohol concentration exceeding 3% in a car during summer could potentially lead to an explosion. Now, we only keep an electronic mosquito repellent in our car, as safety is far more important than repelling mosquitoes.

My family has members with allergic rhinitis, so we never use spray products in the car. Besides the flammability hazard of floral water, its spray particles can also adhere to the air conditioning filter. Once, when I turned on the cold air, there was inexplicable itching in the car. Upon dismantling the filter, I found it covered with various fragrance crystals. Inhaling these into the respiratory tract is highly irritating, especially since inferior floral water can release formaldehyde. If really bitten by mosquitoes, I'd rather apply some ointment than spray the entire car. I recommend using physical mosquito prevention measures, such as car magnetic screens or odorless electric mosquito repellents, which at least won't damage the car's electrical circuits.
