5. Maintenance and Care
Regular cleaning and proper care will ensure the lasting beauty and performance of your AXOR Massaud faucet.
5.1. Cleaning the Faucet
- Use a soft, damp cloth and a mild liquid soap to clean the chrome finish.

The silicone spray nozzles are designed to resist mineral buildup and are easy to clean.
- Periodically wipe the silicone nozzles with your finger or a soft cloth to dislodge any mineral deposits.
