What are the drawbacks of automotive ozone?

[McKathryn]

Automotive ozone has the following drawbacks: 1. Damages materials: As a strong oxidizer, ozone can damage various items. The higher the concentration, the more severe the damage. It can cause green rust spots on copper sheets, age rubber (discoloration, reduced elasticity), making it brittle and prone to breakage, and bleach fabrics. 2. Harmful to respiratory health: Ozone irritates the mucous membranes of human respiratory tracts. At concentrations of 0.5-1ppm, it can cause discomfort such as dry mouth. Therefore, ozone disinfection must be conducted in unoccupied spaces, and the area should remain vacant for at least 30 minutes post-disinfection. 3. Leaves chemical residues: This creates potential hazards and also causes certain degrees of damage to automotive components. Chemical disinfectants generally possess corrosive and bleaching properties, requiring caution when used on car interiors and metal parts.
