Is the Three-Way Catalytic Converter Cleaner Useful for Cars?
2 Answers
For mild three-way catalytic converter blockages, the three-way catalytic cleaner is significantly effective. Here is an introduction to the use of the three-way catalytic cleaner: 1. The function of the three-way catalytic cleaner is to remove chemicals such as sulfur and phosphorus from the surface of the three-way catalytic converter, unclog the exhaust pipe, and restore the activity of the three-way catalytic converter. However, for more severe blockages, the cleaner alone may not be very effective. In such cases, disassembly and cleaning may be necessary, and if there is damage or severe blockage, direct replacement is required. 2. The cleaning solution is drawn into the engine through the intake vacuum tube via a tool, passes through the combustion chamber and exhaust pipe to reach the three-way catalytic converter. At a certain temperature, it reacts chemically with the deposits on the surface of the three-way catalytic converter to achieve the cleaning purpose.
I've used catalytic converter cleaner a few times and found it quite effective, especially for mild converter clogging. As someone who enjoys tinkering with cars, I noticed smoother acceleration and reduced exhaust odor after using it. However, it's not a cure-all solution - if your converter is severely damaged (with melted metal or large cracks), cleaning won't help. For preventive maintenance, adding it to the fuel tank every 20,000-30,000 km can extend the converter's lifespan and save replacement costs. But be cautious about product quality, as some inferior cleaners may damage oxygen sensors. My experience suggests it's worth trying as part of regular maintenance.
