Ensure that your headlamp is clean and dry before and after each use and before storage. DO NOT STORE A WET HEADLAMP. To dry it, turn your headlamp off and open the battery door. Remove the batteries and allow the housing to air dry thoroughly before closing it.

  • Do not artificially heat your headlamp to dry it
  • If your headlamp has been exposed to salt water, it must be rinsed with fresh water then dried and assembled to prevent corrosion
  • Use a mild soap and freshwater rinse to clean the elastic strap
  • Do not clean in washing machine, dishwasher or with a high-pressure hose
  • Do not scrub with abrasive substances or surfaces
  • If the battery contacts are corroded, remove the corrosion by sanding lightly with a fine-grain emery cloth
