The car muffler is part of the exhaust system responsible for making the car quiet, canceling out the noise, collecting the gases and expelling corrosive and highly poisonous waste. Exhaust is naturally dark in color, so the car muffler naturally gets dirty and becomes discolored over time. While not particularly easy to keep clean, a well-maintained muffler will look great, perform better and last longer.

It is best to avoid cleaning the interior of your car muffler. This may cause damage from rust or corrosion and shorten the shelf life of the muffler. Follow these steps to effectively clean the exterior of your muffler.

Step 1: Remove Excess Dirt and Grime

During this project, protect your hands with latex gloves. Use a dry rag or lint-free cloth to wipe off all excess soot and dirt from the exterior of the muffler.

Step 2: Remove Grease and Tough Stains

Add 1 teaspoon of dishwashing soap to a bucket of warm water. Lightly wash the outside of the car muffler with the solution to remove all excess grease and tough stains. Repeat this process until the muffler is clean. If necessary, scrub the exterior with a scrubbing pad, taking care not to scratch the metal. Scratching may cause premature corrosion of the piping or car muffler.

Step 3: Polish the Car Muffler

If your muffler still looks dull or has lost its original shiny appearance, apply a metal polish. Keep in mind that there are different polishes designed for aluminum and chrome. Rub the substance onto the exterior metal surface until shiny.
