### Cleaning Routines

To ensure accurate measurements and optimal performance of your Rhopoint glossmeter, follow these cleaning procedures:

1. **Instrument Optics**:
    - Inspect the optics before each calibration.
    - Remove dust or debris using dry, clean air.
    - Never touch the optics without wearing suitable cotton gloves.
    - If permanent marks or scratches are present on the lenses, return the instrument to an authorized Rhopoint service center[^3].
2. **Calibration Tile**:
    - Inspect the calibration standards before each use.
    - Remove fingerprints and dust with the supplied optic cleaning cloth.
    - If the tile is scratched or damaged, it is not suitable for calibration and must be replaced[^3].

### Annual Calibration Recommendations

- Send your glossmeter and tile to a Rhopoint Approved Service Agent yearly.
- Annual calibration ensures accuracy and compliance with current industry standards.
- Calibration maintains optimal performance and helps meet desired aesthetic and quality standards.
