Step 5: Thoroughly rinse the exhaust system with water to get rid of the cleaning agent.
Step 6: Use a microfiber towel or sponge to dry the exhaust system, making sure there are no water stains left behind.
Step 7: If desired, follow the manufacturer’s directions when polishing any chrome or metal accents on your exhaust system.

Cleaning the Exhaust System’s Interior

A different strategy is needed to clean the exhaust system’s interior. Take these actions:

First, turn on the engine of your car and let it run for a while. The carbon buildup inside the exhaust system will be helped to dissolve by the heat.
Step 2: Shut off the engine and give it a moment to cool.
Step 3: Thoroughly examine the muffler and exhaust pipe. It could be important to seek professional help if you discover considerable carbon buildup or obstructions.
A long, flexible brush or pipe cleaner should be inserted into the exhaust pipe as the fourth step. Scrub the interior gently, sweeping the brush back and forth to remove any carbon buildup.
Step 5: Clean the exhaust pipe and muffler of any loose particles using compressed air or a vacuum.
Step 6: Carry out this procedure for each muffler and exhaust pipe linked to your car.

Tips for Keeping an Exhaust System Clean
