Proper Techniques for Operating a High-Pressure Cleaning Device
Maintain a consistent distance of about 18 to 24 inches from the surface while cleaning. This prevents damage and ensures an even clean. I found that adjusting the distance based on the surface texture is crucial; closer for tough grime, further away for more delicate surfaces.
Proper Stance and Grip
Stand with feet shoulder-width apart, ensuring stability. Your dominant hand should grip the trigger gun firmly, while the other supports the body of the machine. This stance provides better control and reduces fatigue during use.
Cleaning Motion and Technique
Utilise a side-to-side sweeping motion rather than a direct spray. This technique helps dislodge dirt effectively and reduces the risk of streaking. For stubborn stains, maintain the nozzle at a slight angle rather than perpendicular, allowing the force to work along the edge of the dirt.
It’s beneficial to pre-soak heavily soiled areas with a suitable cleaning solution, giving it time to penetrate before applying high-pressure water. Always rinse a small test area first to check for any potential surface damage before proceeding with the entire cleaning project.
