Is It Dangerous to Keep Spray Paint in a Car?

"Keeping spray paint in a car may be dangerous. It is best not to leave it in the vehicle. The paint may contain heavy metals such as lead, cadmium, and iron. Here are the details: Cleaning spray paint: If the spray paint is water-soluble, it can be rinsed off directly with water. However, for non-water-soluble spray paint, you can use cooling oil to clean it. Apply it to the painted area, wait a few minutes, then wipe it off with a cotton ball, and finally rinse with clean water. Alternatively, you can use alcohol, paint cleaners, or other solvents for cleaning. Precautions for using spray paint: Shake the can evenly to ensure the paint is fully vaporized. Focus when spraying, and most importantly, spray evenly. Keep the nozzle neither too close nor too far—about 20 centimeters away—and ensure the spray angle is perpendicular to the surface. Avoid spraying too much at once (or moving too slowly). For deeply damaged areas, spray once, wait a few minutes, and then spray again. If you have never used a spray can before, practice on a scrap piece of material first."

As someone who frequently pays attention to automotive safety, I think keeping spray paint cans in the car is quite risky. During summer, temperatures inside the car can soar above 60°C, causing the gas in the spray cans to expand due to heat, which can easily lead to bursting or leakage. Not only does this dirty the interior, but it could also cause injuries if the can explodes. The chemical solvents released can cause dizziness and nausea when inhaled, especially during long drives, posing significant health risks. A friend of mine once forgot a can in the trunk, and under high temperatures, it swelled alarmingly, making cleanup both difficult and costly. Therefore, I strongly advise against keeping spray paint in the car for convenience. Store it in a cool garage or a well-ventilated area for peace of mind. Small precautions prevent major hazards—maintaining a safe car interior is crucial for daily use. Don’t overlook these risks; developing good habits saves a lot of trouble.

I'm very concerned about the in-car health environment since I spend my daily commute inside. The chemicals in spray paint can volatilize when heated, potentially causing headaches or allergies when inhaled. In summer, the car becomes like an oven, and any leakage or gas emission from the cans can pollute the air, which is especially harmful to children. I've experienced it before—a forgotten spray can under the seat emitted a strange odor that made me feel unwell. Long-term exposure could lead to accumulated health issues, which isn't worth the risk. For safety, it's better to store them in a cool corner outside the home to avoid future troubles. The air quality inside the car directly affects our breathing—don't lose big for small gains. Remember to regularly check the items in your car and promptly remove such things to protect yourself and your family.

After years of driving, I understand the dangers of keeping spray paint cans in the car. High temperatures or vibrations can easily cause leaks or explosions, staining car seats and producing pungent odors. My advice is simple: don't keep them in the car, store them in a shaded area instead. Safety comes first.
