The answer to 'how to clean gutter guards' is to regularly clean and maintain your gutter guards to ensure proper drainage and prevent clogs. This typically involves removing debris, leaves, and other buildup from the surface of the guards using a soft-bristle brush or a garden hose with a spray nozzle.
It's important to be cautious when cleaning gutter guards, as working at heights can be dangerous. Consider using a ladder or other safety equipment, and avoid standing directly on the gutter guards, as this could damage them. If you're not comfortable performing this task yourself, it's best to hire a professional roofing or gutter cleaning service to handle it for you.
