What Are Hard Water Stains?
Hard water contains high levels of minerals like calcium and magnesium. When water evaporates, these minerals are left behind, forming chalky white or brown stains. You’ll often find them:
- On shower glass and tiles
- Around taps and faucets
- Inside toilet bowls
- On car windows and windshields
These stains aren’t just unsightly; they can also damage surfaces over time if left untreated. So let’s get into how we Brits can band together and fight these dreaded hard water stains!!
