Summer Heat: Is Your Car’s Interior Becoming Hazardous?
As the summer season peaks in the Emirates, driving a parked car without preconditioning is a hassle. Beyond discomfort caused due to excessive heat, the toxicity of the car interior is also a rising concern. Processes like off-gassing which occurs when a car interior is exposed to excessive heat can release toxic gases. That said, the fumes from car interiors during summer can be hazardous for the occupants.
Let’s dive a little deeper and elaborate on car interior toxicity during summer.
Reasons for Car Interior Toxicity
Cars are covered in different types of compounds after leaving the manufacturing plant. These compounds are also responsible for generating new car smells. When these compounds are exposed to heat, they start releasing fumes that might be toxic.
The following are the different reasons that can make car interiors harmful during the summer.

Off-gassing of Materials
Off-gassing or outgassing is a process in which compounds trapped inside a material are released when exposed to heat. Synthetic materials used in interiors like car steering and dashboard undergo off-gassing releasing different chemicals that can be toxic.
Release of Volatile Organic Compounds (VOCs)
Materials used in car interiors like plastic, adhesives and leather contain VOCs. These VOCs are released when the temperature inside the cabin increases. Inhaling the VOC fumes can be harmful leading to multiple health issues.
Mould Growth
Excessive heat and humidity inside the car cabin facilitate bacteria and mould growth. Breathing in mould spores and bacteria can cause allergies, respiratory disorders and other issues. In case, mould growth is consistent in your car, here is a step by step guide to remove mould from car interior.
How to Deal With Toxic Fumes from Car Interior
Now that you know if your car interior is toxic during summer or not, let’s move towards preventive measures.
Following are some ways to deal with car interior toxicity during summer.
Avoid Parking in Direct Sunlight
Direct sunlight is one of the major reasons for car toxicity in summer. It is ideal to park a vehicle under a shade when possible. If not a shaded place, you can opt for multi-storey car parking in Dubai and other Emirates offering shaded parking spaces.

Opt for Preconditioning
Parked vehicles are at a higher risk of releasing toxic fumes due to heat. You can install the car preconditioning system which allows you to maintain cabin temperature prior to using it.
Buy Non-toxic Materials
When replacing the car interior, opt for parts that are labelled as non-toxic or contain fewer VOCs. You can browse through these used car accessories for sale in the UAE and choose from an array of non-toxic car parts.
