Step 1: Gather the Necessary Supplies
Before you begin cleaning, gather the following supplies:
– Protective gloves
– Safety goggles
– Rags or paper towels
– Mild detergent or degreaser
– Water
– Scrub brush or sponge
– Metal cleaner (optional)

Step 2: Prepare the Work Area
Ensure that you are working in a well-ventilated area and protect the surrounding surfaces from any potential damage caused cleaning agents or paint.

Step 3: Remove Loose Dirt and Debris
Using a dry cloth or brush, remove any loose dirt or debris from the metal surface. This will prevent the oil or grease from spreading and make the cleaning process more effective.

Step 4: Apply Detergent or Degreaser
Dilute the mild detergent or degreaser with water according to the manufacturer’s instructions. Apply the solution to the oil-stained areas and let it sit for a few minutes. Avoid using harsh chemicals as they may damage the metal surface.

Step 5: Scrub the Surface
Using a scrub brush or sponge, gently scrub the oil-stained areas in a circular motion. Apply moderate pressure to remove the oil, but be cautious not to scratch the metal. For stubborn stains, you can use a metal cleaner specifically designed for removing oil and grease.

Step 6: Rinse the Surface
Once you have scrubbed the surface thoroughly, rinse it with clean water to remove any remaining detergent or degreaser. Ensure that you remove all traces of cleaning agents, as they can interfere with the adhesion of the paint.

Step 7: Dry the Surface
After rinsing, dry the metal surface completely with a clean cloth or allow it to air dry. Moisture can lead to rust formation, so it’s important to ensure that the surface is completely dry before painting.
