I was going with Common Language Runtime.

But google served up a limescale product!!!

The R is for remover.

What does it do that plain vinegar doesn’t do, in terms of limescale?

BristolUK

Quicker and better I believe. But maybe that depends on the build-up

I use vinegar on the inside of the electric kettle, maybe once a year. 100% cleans it, it looks like new. True, you have to leave it a few hours. But, since it’s a food product, I know that all I have to do is rinse it out two or three times and I can safely use the kettle. I wouldn’t like to use that chemical cleaner on the kettle in the same way.

I double checked with my MIL who has also used vinegar.

Apparently she's used it on kettles and coffee pots. She's 86 this year and still going strong.

She even uses it for her dentures

If I had dentures I’d do that too.

Availability of vinegar is one of my pet peeves about Britain. In the US, and I’m sure Canada too, they sell it in supermarkets by the gallon, and it’s cheap, I think about $3 maybe? In England, it comes in cute little 568ml glass bottles for £2 or £3; so much more expensive. Why the difference? I think, traditionally, Americans do a lot of food preservation, canning fruit and veg. The British just go to Tesco for their food. Also, though, vinegar is hugely popular in the US for cleaning, showers, kitchen sinks, kettles, etc.

It does tend to be white vinegar here. Quick comparison on Walmart Canada, 4l white = $2.47 and 500ml malt = $1.47 (500ml is the biggest size for malt ....well, the only size)
