Where possible, you should always try to keep your headlamp dry and dust-free. If you have been working in dusty or dirty conditions, make sure to brush it off. If you have been working in the rain, dry it off properly. Store it in a secure location where it is not going to get damaged. Many headlamp straps are detachable, allowing you to wash them if they get dirty or sweaty. However, you can rest assured that it is difficult to break headlamps as they are durable and made to last for years. Related Posts: Best Work Light, LED Work Lights and Mechanic Flashlights.
