Step-by-Step Cleaning Process

1. Safety First: Disconnect Battery

For safety reasons, disconnect the negative battery terminal to prevent any electrical accidents.

2. Cool Down the Engine

Allow the engine to cool completely before cleaning. Hot metal can cause burns and damage the radiator fins.

3. Remove Loose Debris

Use the soft-bristled brush to gently remove any loose dirt, leaves, or debris from the radiator fins. Avoid using sharp objects or high-pressure water, as they can damage the delicate fins.

4. Rinse with Water

Connect the garden hose to a nozzle and gently rinse the radiator fins with a stream of water. Use a low-pressure setting to avoid bending or breaking the fins.

5. Apply Dish Soap Solution (Optional)

For stubborn grime, mix a solution of dish soap or mild detergent with water. Apply the solution to the radiator fins using a spray bottle or sponge. Let it sit for a few minutes to loosen the dirt.

6. Brush Away Dirt

Use the soft-bristled brush to gently scrub away the loosened dirt. Work in small sections, brushing in the direction of the fins.

7. Rinse Thoroughly

Rinse the radiator fins thoroughly with water to remove all soap residue. Ensure that all dirt and debris are washed away.

8. Use Commercial Radiator Cleaner (Optional)

If necessary, apply a commercial radiator cleaner to remove any remaining dirt or scale. Follow the instructions on the product label carefully.

9. Rinse Again

Rinse the radiator fins thoroughly with water to remove any traces of the radiator cleaner.

10. Dry the Fins

Use a clean, dry cloth or compressed air to dry the radiator fins. This will prevent water spots and corrosion.

11. Reconnect Battery

Reconnect the negative battery terminal to complete the cleaning process.
