# Cleaning the Laser Scanners

## Procedure

> [!WARNING]
> **Caution: Mechanical and chemical hazard.**
> 
> - Damage to the laser scanner and/or internal electrical components.
> - Only clean if necessary with a clean and dry microfiber cloth. Always wipe the optical surface along its curve, not top-to-bottom.

1. Remove dirt, dust, and water.

If the laser scanner is dusty or dirty use an air blower or soft-bristled brush to remove dust and dirt from the optical surface. If it is wet, gently dry it with a clean and dry microfiber cloth.

2. Polish the optical surface.

Use a clean and dry microfiber cloth to polish the optical surface. Always wipe the optical surface along its curve, not top-to-bottom.
3. Deep clean if necessary.

If the optical surface is still dirty, put a few drops of isopropyl alcohol on the microfiber cloth and polish the lens again. Do not apply isopropyl alcohol directly onto the optical surface of the laser scanner.
