can catalytic converter be cleaned

How to clean the three-way catalyst? How to maintain it?
Here are three solutions
The three-way catalytic converter is the most important off-board purification device installed in the automobile exhaust system. Since this catalyst can convert the three main harmful substances in the exhaust gas into harmless substances at the same time, it is called three-way.
Many auto repair shops have three-way cleaning agents, which are three-way catalytic cleaning agents, but the cleaning effect is average. To a large extent, it only gives the car owner a psychological comfort. The most effective way is to remove it for cleaning, but it is time-consuming and laborious. Therefore, it is still necessary to do a good job of maintaining the three-way catalytic converter in normal times.
1. Do not use inferior gasoline
The oil problem is the biggest cause of damage to the oxygen sensor and the three-way catalytic converter. When the gasoline contains more lead or other impurities, some impurities will remain after combustion, and some of them will be discharged into the three-way catalytic converter along the exhaust pipe. If this continues for a long time, the three-way catalytic converter will be blocked.

2. Avoid long-term idling
Try to ensure the normal operation of the engine and reduce long-term idling. If the fuel is not fully burned, it will directly enter the exhaust system. If the idling time is too long, the exhaust system will continue to heat up, thereby burning the three-way catalytic converter.
3. Be careful not to touch the ground
The material of the three-way catalytic converter is very fragile and will break if it encounters a collision, which will cause the catalyst and exhaust system to be blocked, so be careful not to touch the ground. The owner should regularly check the three-way catalytic converter to see if there is any damage on the surface. After the temperature of the three-way catalytic converter drops, you can knock on the metal surface with your hand or hear a sound similar to ceramic breaking inside while driving, which means that the catalyst is damaged and needs to be replaced.
