How do you clean a car’s AC condenser?
My car’s air conditioning hasn’t been working as effectively recently. I asked my mechanic friend to take a look, and he said it looked and sounded fine but that the condenser could use a cleaning. He briefly explained how to clean the condenser, but honestly was a bit over my head. What’s the best way to clean a car’s AC condenser?

- Garbage bags and painter’s tape

- Personal protective equipment like rubber gloves, safety goggles, and a mask
- Turn off your car and let the engine cool
- Remove the front bumper by undoing the screws, bolts, and fasteners that hold it in place; consult your owner’s manual for specific instructions

- Rinse the condenser using a hose or spray bottle and allow it to completely dry
