Maintenance
Regular maintenance will help preserve the finish and functionality of your CASAINC shower system.
- Cleaning the Finish: The matte black finish is designed to be fingerprint resistant. Clean regularly with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Preventing Mineral Buildup: To prevent calcium and lime buildup, especially on the shower head nozzles and body jets, wipe them clean after each use. For stubborn deposits, use a solution of equal parts white vinegar and water, applied with a soft cloth. Do not soak components in vinegar.
- Nozzle Cleaning: The silicone nozzles on the shower head and body jets are designed for easy cleaning. Simply rub them with your finger to dislodge any mineral deposits.
- Filter Maintenance: Periodically check and clean the inlet filters on the thermostatic valve to ensure optimal water flow. Refer to the installation guide for instructions on accessing these filters.
