Maintenance and Care
Proper care will ensure the longevity and aesthetic appeal of your Ideal Standard shower mixer. The chrome finish is durable but requires gentle cleaning.
Cleaning Instructions:
- Use only mild soap and water with a soft cloth or sponge.
- Rinse thoroughly with clean water after cleaning to remove any soap residue.
- Dry the surface with a soft, dry cloth to prevent water spots and maintain shine.
Avoid:
- Abrasive cleaners, scouring pads, or harsh chemicals (e.g., ammonia-based cleaners, bleach, acidic cleaners) as these can damage the chrome finish.
- Leaving water spots or soap residue for extended periods, as this can lead to mineral buildup.
