Top 10 Catalytic Converter Cleaners

The catalytic converters in our vehicles do an excellent job of cleaning up the gaseous emissions made by our cars and making them less harmful to the environment. They do this by creating a redox reaction that oxidizes some of the more harmful gases and so rendering them neutral.

Needless to say, this means these converters work pretty hard and need a thorough cleaning as part of your standard maintenance routine to keep them running at maximum capacity. There are a lot of cleaners available, but do they really do a good job?

Like everything in life, some do a better job than others. In this post, we have narrowed down the list to the ten best catalytic converter cleaners. We rated them on effectiveness, value for money and ease of use.

We do suggest checking your car’s manual to find out what type of cat converter it has. Also, check whether or not the cleaner can be used in your car’s system.
