* Use the soft-bristled brush to gently agitate the cleaner and remove stubborn dirt.
**4. Rinse Engine Cleaner:**

**5. Dry the Engine:**
* Use a clean towel or microfiber cloth to dry the engine as much as possible.
* Pay special attention to areas where water may accumulate, such as the spark plugs and alternator.

Additional Tips
* Use a spray nozzle with a wide angle to spread the water or cleaner over a wider area.

* If the engine is particularly dirty, consider using a power washer with a dedicated engine cleaning attachment.
* Allow the engine to idle for a few minutes after cleaning to dry out any remaining moisture.
* Regularly cleaning the engine can help prevent rust, corrosion, and performance issues.
Troubleshooting
* **Water in Electrical Components:** Turn off the engine immediately, disconnect the battery, and dry the components thoroughly. Seek professional help if necessary.
* **Loose or Disconnected Parts:** Tighten any loose parts and reconnect any disconnected wires or hoses.
* **Leaking or Damaged Components:** Park the car and call for assistance immediately. Driving with a leaking or damaged engine can be dangerous.
