Prolonged rain is not a direct cause of car damage, but water, dust, mud and high humidity can affect some parts if the car is often parked outdoors. After heavy rains, car owners should check and clean places where water easily accumulates.
Paint and exterior
These are areas directly affected by weather. When rainwater combines with dirt and pollutants clinging to the body of the car, after the water evaporates, it can leave residue on paint, glass or external details. If left for a long time, these stains will be more difficult to clean.
Therefore, after heavy rains, especially when the car is covered in mud or dirty water, the car owner should clean it. Do not use a dry towel to rub hard on the surface with a lot of dust because it can create small scratches on the paint layer.
Closed doors, trunks and glass
These rubber details are responsible for preventing water and dust from entering the car compartment. Prolonged rain makes the seat area often damp, and easily accumulates dust, leaves and impurities.
The gasket itself is not easily damaged after just a few days of rain. However, if it has aged, cracked, or deformed, the possibility of water entering the cabin will increase. Car owners should check the door edges, dry the water stains and handle it early if any abnormalities are detected.
Brake system
The brake system may have a thin rust layer on the disc surface after the car is in a damp environment. This is usually not a serious phenomenon and the rust layer may disappear after a few brakes when the car operates again.
However, after a long period of not operating, the driver should try braking at low speed in a safe area. If abnormal friction sounds appear, the car is pulled off or the braking effect is reduced, it is necessary to check the braking system before continuing to use.
Undercarriage and metal details
This is an area that is difficult to observe but is frequently exposed to water and mud. bolts, supports and details with reduced protective layers may show signs of oxidation over time.
In particular, vehicles that frequently pass through flooded roads or areas with a lot of mud need to have their undercarriage cleaned after operation. Dirty water staying for a long time can make the corrosion process faster.
Drainage and slits on the body
Leaves, soil, or small trash can be stuck at the foot of glass, door, trunk, or sunroof, preventing water from flowing properly. When blocked, water can stagnate and flow into unwanted locations.
If the car is often parked under trees, car owners need to check these drains after prolonged rains.
Finally, the interior compartment needs to be checked if any abnormalities appear. Water leaking through the gauze, glass, sunroof, or drain can cause floor mats and seat sheets to become damp and develop a foul odor. In case of excessive water intrusion, some jacks and electrical systems arranged under the floor are also at risk of being affected.
Therefore, parking a car in the rain does not mean that the car will break down quickly. However, for vehicles that often have to park outdoors, cleaning the body, checking the gauze, drainage, and undercarriage after heavy rain will help limit the impact of the weather during the rainy season.
