What is the difference between parking in a garage and outdoors?

[Roy]

Here are the differences between parking in a garage and outdoors: Sun exposure: Prolonged exposure to sunlight will inevitably oxidize the car's paint surface, causing it to lose its luster. Additionally, many car components are made of plastic, which is prone to aging under intense sunlight. Parts such as lamp covers and tires will have their lifespan reduced due to prolonged sun exposure. Rain exposure: Rainwater can cause rust on components like the air conditioning condenser and chassis, thereby shortening the lifespan of the air conditioning system. Rainy conditions can also lead to water ingress in the headlights. If moisture is found inside the headlights, it can affect nighttime driving. Low temperatures: Low temperatures can increase the viscosity of engine oil, potentially causing a sudden rise in oil pressure that may damage components and seals, posing significant safety risks. In winter, frost and ice formation on the windshield are common due to the temperature difference between the inside and outside of the car. To mitigate or avoid this, it is advisable to open the car doors for a few minutes before locking the car at night, allowing the interior temperature to equalize with the outside temperature, thus reducing or preventing the issue of difficult-to-remove frost or ice in the morning.
