A catalytic converter is important for your vehicle as it converts pollutants (such as carbon monoxide, hydrocarbons, nitrogen oxides, and other exhaust engine emissions ) that are toxic into lesser harmful exhaust gases through vehicle emission control.
The catalytic converter does this by catalyzing a redox reaction to lessen the toxic pollutants in these gases.
This converter is mostly used in internal combustion engines, which are fueled, by diesel, petrol, or gasoline.
The only thing is three-way catalyst converters need regular cleaning and maintenance so that they can perform at a high level.
You should keep them clean so that they can work more efficiently and increase their shelf life.
As such there are three different methods recommended to clean the converter from the core.
The initial stage of cleaning the converter is to remove the core from it.
It is very simple as you just have to loosen the retaining clamps and bolts that are at the end of the flanges.
Few converters do not have bolts because of their small diameter. They can be removed from the exhaust system easily.
While removing a bigger converter is careful, that gasket is not damaged. If it is damaged, then it might be a big problem.
Once you have successfully removed the converter, you can choose any of the three methods to clean it. The first method is to use compressed air.
It will remove light accumulation on the core of the converter.
A core generally has aches and related contaminants on it. Make use of a rubber-tipped air nozzle and target the airflow on the outlet and inlet faces of the core.
While performing cleaning it is suggested to wear a dust earmark or respirator of high quality. Initial target at the outlet area and compress the air in each cell.
After cleaning of outlet, focus on the inlet and clean in a similar way.
If the core of not clean after the first process, then keep repeating the procedure. You can make use of a steam cleaner as a substitute for the air compressor.
The second method is for heavy accumulation of core.
One has to remove the core of the converter and place it in the oven. The oven should be capable of achieving a 1050 °F temperature for almost 2 to 3 hours.
It is best to use a heat-treating or ceramic oven.
Remember, not to exceed the recommended temperature and the time. One should strictly follow the instruction to be safe and secure.
The third method is to soak the core of the catalyst converters in a solution of State 999 or Super Concentrated Gunk detergent.
Keep the core in the solution for about one hour so that heavy accumulation on it can be removed easily. One can also use other efficient detergents for soaking.
After removing the core from the solution, blow-dry it.
Keep repeating the procedure until the car gets clean. Once the core is clean, attach it to the converter.
It is recommended to install a new gasket if needed or reuse the existing one.
