How to Clean Headlamp Glass Without Damaging It
Use a clean soft cloth and the care instructions for your exact lamp. Avoid solvents and abrasives unless the manufacturer explicitly permits them.
Remove loose grit first
Blow away loose dust or lift it with a clean soft brush. Rubbing grit across the lens can leave marks.
Wipe the lens gently
Use a clean microfibre or other soft lint-free cloth. For smears, lightly dampen the cloth with water rather than spraying liquid directly onto the lamp.
Avoid harsh cleaners
Do not use abrasive pads, household glass sprays or solvents unless the manufacturer approves them for that lens material and coating.
Dry and inspect
Dry the surface and check the lens, seals and charging port for damage before use. If moisture entered the housing, follow the maker guidance before switching the lamp on.
