Imagine your water is a busy highway, and hard water is just that highway packed with mineral trucks—specifically calcium and magnesium. It’s not bad for you to drink, by the way.
But here’s where it gets interesting: those minerals don’t like to play nice with your soap. Instead of lathering up into a fluffy cloud, soap mixes with hard water and creates a sticky residue called soap scum.
Think of it like trying to wash your hands with a mix of sand and grease. Not exactly the spa treatment you were hoping for, right?
