How to Clean a Clogged Catalytic Converter

A clogged catalytic converter can cause your vehicle to experiece lower engine performance levels and poor gas mileage. It will also be unable to control the harmful emissions released into the air by the vehicle exhaust.

Step 1 – Safety

Be sure your vehicle is parked on a hard, flat and well lit surface. Open the hood and lift the prop rod. Secure the prop rod in position to keep the hood of the car open. Put on your protective eye wear before you begin.

Step 2 – Removing the Catalytic Converter

Use a wrench to loosen and remove the bolts that secure the converter into position. Place the bolts in a safe place until you need them again. Remove the catalytic converter from your exhaust system.

Step 3 – Inspecting the Converter

Inspect the converter for any damage. Shake the converter and listen for any noises.

Step 4 – Cleaning the Converter

Use a cleaning cloth to wipe away any residue from the face of the converter. Use the power washer to force any built up debris out of the converter. Force the water into the inlet and outlet pipes.

Step 5 – Allowing the Converter to Dry

Allow the catalytic converter enough time to dry completely before you position it back into the exhaust system.
