Maintenance
Regular maintenance will help preserve the finish and functionality of your GOXIUHAN shower system.
Cleaning the Finish
The multi-layer Matte Black finish is designed to resist daily scratches, corrosion, and tarnishing. To clean, use a soft cloth with mild soap and water. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
Cleaning the Shower Head Nozzles
The rainfall shower head features soft silicone spray holes. To remove calcium and lime build-up, simply wipe the nozzles with your finger or a soft cloth. This helps maintain consistent water flow and prevents clogging.
