The 10 Best Products to Support Catalytic Converter Cleaning and Performance
Catalytic converters play a pivotal role in your vehicle's operation. They are a part of the exhaust system that minimizes harmful pollutants released from your car's tailpipe. Catalytic converters take chemicals like hydrocarbons, carbon monoxide, and other similar substances to convert them into water vapors and carbon dioxide that are safer for the environment.
What is a Catalytic Converter Cleaner?
Catalytic converters typically last about 100,000 miles before they may require replacement, but many can last longer. Unfortunately, these instruments can get clogged, and as a result, they might need to either be cleaned or replaced.
A catalytic converter or fuel system cleaner is typically a formula you can put into your fuel chamber that clears out carbon deposits in your catalytic converter and likely the rest of your fueling system — including fuel injectors. The signs that it may be time to clean or replace your catalytic converter include heightened fuel consumption, dark exhaust smoke, and the smell of sulfur from your exhaust pipe.
Depending on how severe the clog or damage to your catalytic converter is, a fuel system or catalytic converter cleaner can help you improve this component’s function. There are a variety of options out there, and here are some picks that we recommend.
