Maintenance

Cleaning the Finish

• To maintain the matte black finish, clean regularly with a soft, damp cloth.
• For stubborn spots, use a mild soap and water solution.
• Do not use abrasive cleaners, harsh chemicals, or scouring pads, as these will damage the finish and void the warranty.
• Rinse thoroughly and dry with a soft cloth to prevent water spots.

Cleaning Silicone Nozzles

• The rainfall shower head and handheld shower head are equipped with silicone nozzles.
• To remove mineral deposits (limescale), simply wipe the nozzles with your finger or a soft cloth. This flexible design allows for easy cleaning and prevents clogging.
• For more severe buildup, a solution of white vinegar and water can be used. Soak the shower head (if removable) or apply the solution to the nozzles, then scrub gently and rinse.
