Wow I just learned of Hard Water vs Soft Water. I googled and yeah its a moderately hard Water area. So I assume this is normal (or at least nothing to be alarmed about)?
Yup, completely normal. I have hard water and my kettles get calcium buildup after a handful of uses. Soak with white vinegar to remove the buildup. Or if you're like me and forget until last second, boil 50/50 vinegar/water and deal with the vinegar smell, lol.
Ahh thank you! Kinda freaked out seeing so much weird stuff on the water's surface. Out of curiosity would regular consumption of such water have any adverse effects?
I'm guessing your UK, but in America it's a lot worse and most people need salt exchangers.
Just think of it as "mineral water".
But I think other people talking about residual fat are probably right. If you have hard water, you'll notice a white chalky substance on faucets and stuff, or if you leave a glass of water out to evaporate, it'll leave behind the minerals.
Very good to know! Just trying to avoid potential stomach upsets while overseas. I'll be gone in a week or so, so not concerned about the other stuff :P
Scaleaway Household Descaler for £1.35 will (dis)solve the problem in less than one hour. I'm never going back to using vinegar, this stuff works much better. ;)
