Ozone is a strong oxidizing agent that can damage various items. The higher the concentration, the more severe the damage to items. It can cause green rust spots on copper sheets, aging, discoloration, and reduced elasticity of rubber, leading to brittleness and breakage, as well as bleaching and fading of fabrics. Ozone also irritates the mucous membranes of the human respiratory tract. At concentrations of 0.5-1 ppm, it can cause discomfort such as dry mouth. Therefore, ozone disinfection must be conducted in the absence of people, and entry should be avoided for at least 30 minutes after disinfection. More details are as follows: 1. According to international standards, concentrations of 0.5-1 ppm can cause discomfort such as dry mouth; 1-4 ppm can cause coughing; and 4-10 ppm can cause severe coughing. 2. Ozone disinfection is an allotrope of oxygen, gaseous at room temperature, highly reactive chemically, very soluble in water, and has extremely strong oxidizing capabilities. 3. The oxidizing power of ozone can be used for sterilization and disinfection. When ozone encounters bacteria, it immediately undergoes an oxidation reaction, thereby achieving functions such as sterilization, mold removal, odor elimination, and decomposition of harmful gases. The oxygen left after the reaction does not pollute any items in the car. 4. The ozone sterilization and disinfection process takes 15 to 30 minutes. After completion, the car owner should not enter the vehicle immediately but should leave the doors open for a few minutes to allow any remaining ozone to fully react before entering. Due to its strong oxidizing properties, ozone can pose certain hazards to human health.

I've used ozone disinfection a few times before, and honestly, the effect isn't as good as advertised. The smell is pungent, and it takes several hours of ventilation before people can enter, which is particularly unfriendly to the elderly and children. The most annoying part is its strong corrosiveness—my genuine leather seats started to fade and discolor after just two treatments, and the steering wheel cover became hard and sticky. A friend at the repair shop mentioned that improper ozone concentration control can also damage wiring, especially in new cars with lots of electronic components. If you really need to use it, it's best to go to a professional disinfection service—definitely don't buy a machine and try to do it yourself.

As a mom who frequently takes kids out, I don't recommend ozone disinfection. The lingering smell after treatment makes children cough badly - doctors said it's due to excessive ozone concentration irritating the respiratory tract. Interior damage is also noticeable: light-colored roof linings turn yellowish, and plastic door handles become brittle and crack easily. What's worse, the disinfection isn't thorough - dust in hard-to-reach corners remains untouched. Now I've switched to sun exposure plus steam cleaning, which is both cost-effective and reassuring.

After the last disinfection, I noticed the dashboard was squeaking. Ozone is too oxidizing – the rubber seals in the car cracked and started leaking within half a month, and the center screen developed frost-like patterns. A professional mechanic opened it up and found white oxidation layers on the wire harness connectors. Plus, ozone decomposes quickly and isn’t effective against stubborn mold. The musty smell in the AC ducts returned after just three days. Each session also cost over 200 yuan to replace the AC filter, making it really not cost-effective.

I've tried ozone disinfection on all three cars at home, and overall, the drawbacks outweigh the benefits. The leather steering wheel became sticky after treatment, and the fabric seats noticeably darkened. The worst part is the lingering odor—my wife gets dizzy when riding in the car. The repair shop owner mentioned that frequent use can cause premature aging of interior plastics. He's handled several cases where window regulators got stuck due to ozone disinfection. Now, I use UV disinfection lamps instead. Though it takes more time, it's much safer.

The biggest pitfall of ozone disinfection is that it only addresses the symptoms, not the root cause. The surface may smell fresh afterward, but biscuit crumbs in seat crevices and mold spots on the AC evaporator remain untouched. Its strong oxidizing properties also accelerate interior aging—my car's ceiling fabric started pilling within three months, and the metal parts of seatbelt buckles rusted. Not to mention it's extremely unfriendly to asthma sufferers, and excessive concentration may even cause electrical shorts. You're better off frequently opening windows for ventilation and scheduling regular deep cleaning.
