Hardness Difference: 127 mg/L
Istanbul is significantly harder than Amsterdam — a difference that has major household implications. Appliances, boiler warranties, and detergent costs will differ substantially.
Moving from Amsterdam to Istanbul?
If you're relocating from Amsterdam to Istanbul, expect visible limescale on taps and shower heads within weeks. You'll need to recalibrate your dishwasher's salt setting, increase kettle descaling frequency, and check your boiler warranty requirements. A shower filter and under-sink scale inhibitor are worth considering immediately.
