Why Use Cotton Swabs When Driving?

[AndrewAnn]

Using cotton swabs can help clean the interior of the car, such as the air vents of the air conditioning system. Here are some precautions for using car air conditioning: 1. Minimize air conditioning use during low-speed driving: Using the AC at this time forces the engine to operate at higher RPMs, which can shorten the lifespan of both the engine and the AC compressor. 2. Keep the air intake unobstructed: When placing items, avoid blocking the air intake area. If the intake is blocked, airflow in the AC system will be restricted. 3. Clean the air vents regularly: Vents tend to accumulate dust, and frequent cleaning prevents odors and ensures good air quality inside the car. 4. Avoid turning off the AC after engine shutdown: If the AC is turned off only after the engine is shut down, the next time the vehicle starts, the engine will bear the AC's load, increasing its burden. High-load operation can damage the engine. When using the AC again, it's best to wait two to three minutes after starting the vehicle before turning on the AC.
