Gas additives to clean catalytic converter
Catalytic converters have been around for a long time. They first introduced converters in the mid-seventies, on American vehicles. The catalytic converter may go unnoticed, until it fails. Replacement of most catalytic converters will be very expensive. Fortunately, most failures are also preventable.
Why does a catalytic converter cost so much?
A catalytic converter has no moving parts. They consist of a metal shell and a ceramic honeycomb through which exhaust gasses pass. The honeycomb provides support for the catalyst. The catalysts are the heart of the converter. Catalysts in modern catalytic converters contain noble metals. They normally use platinum, palladium and/or rhodium. Because of the scarcity of these metals, they are very expensive. An original equipment catalytic converter requires a high content of these metals. This is why a quality replacement converter is so expensive.
What does a catalytic converter do?
The catalytic converter changes toxic chemicals in exhaust to less toxic gas. Untreated exhaust gas is largely nitrogen oxides, carbon monoxide and unburned hydrocarbon. The catalyst in the converter helps convert these into much less toxic carbon dioxide, nitrogen and water. It does this by chemical reaction and a great deal of heat.
What causes catalytic converters to fail?
Unburned fuel or contaminants entering the converter, can cause the heat to rise out of control. These contaminants enter through the exhaust. Excessive heat can melt the honeycomb support.
An overheated honeycomb may break and cause a rattle. It can also block the exhaust flow. This results in the exhaust being restricted. Restricted exhausts result in a loss of power, fuel mileage, overheating and usually a check engine light.
Common causes of contaminants entering the exhaust
Coolant, from leaking intake-manifold gaskets, is often drawn into the engine. A leaking head gasket has much the same effect. The chemicals in the engine coolant quickly contaminate the catalyst and cause failure. Promptly addressing any loss of coolant helps prevent this expensive problem.

How to clean catalytic converter
No, the oxygen sensors are not in the converter itself, but upstream in the exhaust, and sometimes one on the rear of converter in the exhaust, but not in the converter.
There is no additive that can do anything for the converter. A well-maintained clean running engine kept in good tune is your only insurance against a plugged or failed converter.

NO WAY!!! otherwise you'd see tons of commercial products for cheapper than the cat, but still expensive enough to cause a problem to average consumers.
