Will seafoam clean a catalytic converter?

Seafoam, a popular engine cleaner, may not be the most effective solution for cleaning a clogged catalytic converter and could potentially cause harm. Here’s what you need to know:

Limited effectiveness: While Seafoam can remove mild carbon deposits from engines and intakes, it’s not designed to handle the tougher clogs commonly found in catalytic converters. These clogs often involve hardened deposits or physical damage that require more specialized cleaning methods.

Potential risks:

• Backfiring: Inhaling Seafoam fumes during cleaning can potentially lead to engine backfiring, posing a safety hazard.
• Oxygen sensor damage: Introducing Seafoam through the intake manifold can damage oxygen sensors in some vehicles.
• Environmental impact: Improper use or disposal of Seafoam can harm the environment.

Safer and more effective alternatives:

• Professional cleaning: Consult a qualified mechanic for professional catalytic converter cleaning using specialized equipment and methods.
• Fuel additives: Consider using catalytic converter cleaner fuel additives, specifically designed for this purpose. However, their effectiveness can vary.
• Replacing the converter: In severe cases, a complete replacement might be necessary.

Remember: Always prioritize safety and follow manufacturer instructions when using any cleaning products or additives.

I hope this information helps you make an informed decision about cleaning your catalytic converter!
