- Nylon brush
- Soft bristle brush
Make sure that you have all of these materials on hand before you start cleaning.
Cleaning the Surface
The first step in preparing the affected area is to clean the surface. Use a soft bristle brush to remove any loose dirt or debris from the metal surface. If the surface is heavily soiled, you may need to use a cleaning agent to remove the dirt. Apply the cleaning agent to a clean cloth and gently wipe the surface. Be sure to follow the manufacturer’s instructions for the cleaning agent.
Once the surface is clean, use a nylon brush to scrub the affected area. This will help to remove any remaining dirt or debris, and will also help to loosen the paint. Be sure to use a gentle touch, as you don’t want to damage the metal surface.
After scrubbing the affected area, use a clean cloth and wipe away any remaining dirt or debris. This will help to ensure that the surface is clean and ready for the next step in the cleaning process.
