How to Clean a Car's Air Conditioning Radiator?

The outermost layer covered is the condenser, not the radiator. Simply rinsing from the outside with a water gun won't achieve an effective cleaning. Remove the radiator for cleaning. Separate the radiator and condenser, then use a brush or high-pressure water gun to remove dirt from the gaps, followed by rinsing the surface with clean water. It's best not to attempt cleaning the radiator yourself. Removing the radiator is quite troublesome, and even repair shops are reluctant to disassemble the entire radiator for cleaning, so supervision is necessary.

Last week when I turned on the AC, there was a musty smell. After checking, I found out the evaporator was dirty and needed cleaning. Here's how to DIY: Buy a bottle of car AC cleaner, start the engine but don't turn on the cooling, set the fan to maximum speed, locate the air intake (usually under the windshield), and spray the cleaner in 2-3 bursts. Wait 10-15 minutes for the liquid to flush out the dirt, then turn off the engine and wipe away any residue with a damp cloth. It's simple and cost-effective. Remember to clean it every six months to keep the AC fresh and prevent pipe blockages. Before DIY, ensure the car is parked securely to avoid damaging the electrical circuits.
