Step 3. Start with the headlamp

Get the headlamp out and cover it with a towel after reading the owner’s instructions to avoid any form of exploration or mishap. 

Now, grab a stick that may be attached to the magnet and move it to the inside of the lens. Now, move the magnetic cleaning tool around until all of the dirt and debris is gone.
