How to Remove Carbon from an Exhaust Port?

Removing carbon buildup from an exhaust port involves a combination of mechanical and chemical methods to safely and effectively clean the area. Here's a breakdown of the process:

Steps to Remove Carbon Buildup

1. Initial Scraping:

   • For stubborn carbon deposits, start by carefully scraping the carbon using a putty knife.

2. Mechanical Cleaning:

   • Use a wire brush or steel wool to further remove the loosened carbon.
   • Important: Avoid applying excessive pressure to prevent damage to the metal surfaces of the exhaust port.

3. Solvent Application:

   • Clean away the remaining carbon residue with a suitable solvent. This helps dissolve any remaining deposits.

4. Final Smoothing:

   • Use fine steel wool to smooth out any rough spots left behind after the solvent cleaning. This ensures a clean and even surface.
