It did absolutely nothing in the kettle despite the fact that the instructions were followed to the letter.
waste of money

Very effective! It removed all the salts from the walls of the kettle that had accumulated for months like a rock and wouldn't come off even with scrubbing with wire! After boiling, with a simple wipe with a sponge all the salts dissolved like dust and the kettle became like new!

It does a good job. It smells a bit strong but after a few washes, the smell goes away. It's worth every euro.

It cleans from the salts but it has a terrible smell. With the kettle, no problem, but with the espresso machine, I have a big problem. I have done 3-4 rinses with clean water, I have made 10 coffees in case the smell goes away but NOTHING!

It seemed fine to me to work, and it has clear instructions in case you don't know what to do like me. Also, it accidentally flew into my eye and I didn't die, so 5/5 :')

Get it without a second thought. For a budget home espresso machine, it does its job and more! The instructions are very clear

For years, I used to clean my French press and espresso machine with vinegar and water. This year, the flow of coffee was in bad condition. It would take 15 minutes for the French press to make 2 cups of coffee. So, I also bought this descaling liquid, followed the instructions, and after doing 4-5 clean rinses with water, I can say that both the French press and espresso machine are unrecognizable. It truly brought the coffee makers back to life. I will definitely buy it again next year for their descaling.

I bought it again to clean our filter coffee machines and espresso machine, and it did a great job again! This year, I also tried it on our kettle, which had started to accumulate salts, and it made it look brand new! It reflects your face! It's a nice cheap product that does its job.

Very good product. It descales and the most important thing is that it doesn't leave any smell (as long as it is rinsed well after descaling)

Excellent product, I cleaned the kettle and espresso coffee maker from limescale and they are like new. I recommend it
