5. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your Bristan shower handset.
Cleaning the Handset:
- Chrome Finish: Clean the chrome finish regularly with a soft cloth and warm soapy water. Avoid abrasive cleaners, scourers, or chemical cleaning agents, as these can damage the finish.
- Rub Clean Nozzles: The handset features 'Rub Clean' nozzles. To remove limescale build-up, simply rub the silicone nozzles with your finger or a soft cloth while water is flowing. This helps maintain a consistent spray pattern and prevents blockages.
- Deep Cleaning: For stubborn limescale, a mild descaling solution designed for bathroom fixtures can be used, but always follow the manufacturer's instructions and rinse thoroughly immediately after application.
Always ensure the handset is thoroughly rinsed with clean water after cleaning to remove any cleaning product residue.
