6. Manutenzione
Regular cleaning and maintenance will ensure the longevity and optimal performance of your GROHE Rainshower 310 Smartactive Cube Head Shower.
- Pulizia della finitura: The GROHE StarLight technology ensures a long-lasting chrome finish resistant to dirt and scratches. Clean the surface with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome fixtures. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Anti-Limescale System (SpeedClean): The integrated SpeedClean nozzles are designed for easy limescale removal. Simply wipe the silicone nozzles with your finger or a soft cloth to dislodge any mineral deposits. This should be done regularly, especially in hard water areas.
- Guida all'acqua interna: The Inner WaterGuide insulation keeps hot water away from the surfaces, preventing them from overheating and extending the product's lifespan. No specific user maintenance is required for this feature.
