- Secure Loose Items: Make sure to remove or secure any loose items on the car, such as mirrors and antennas, to prevent them from being damaged or becoming projectiles during cleaning.
- Inspect Your Equipment: Regularly check the pressure washer for leaks, frayed hoses, or damaged nozzles to ensure it operates safely and efficiently.
