My wife was trying to clean our kettle
I said, it needs CLR
she asked what CLR is
I said Calcium Lime and Rust. There is also Lime-Away.
She put the CLR in there. Then she washed it out many times. All of the mineral deposits washed away. She rinsed it out with water many more times, and then eventually cleaned it with vinegar after rinsing it many times. At least, I think that’s how she cleaned it. She’s the kettle cleaner, I don’t know much about it, other than that CLR exists.
It was very clean for a few months.
We got a regular kettle after that
Not sure where OP lives, but I’m in the UK and have to descale my kettle at least twice a year.
According to the internet, my area is around 297ppm.
Never heard of CLR, but we get descaling sachets from the supermarket - I assume it’s similar? Either way, they’re dirt cheap and quick to do, so it’s not really an issue.
I learned about CLR because of a similar product, called Lime-Away
“Lime, Calcium and Rust, Lime-away is a must!”
So when I went to the store to find Lime-away, I saw CLR, which is titled just like the Lime-away commercial, and I just used that instead. I don’t know if I’ve ever even tried Lime-away.
Then, years later, I met my wife.
Have 50 ppm in my city, Gothenburg, Sweden. It wasn’t until I was an adult that I learned about descaling etc. because it’s just never (or very rarely) needed here.
