De-scsles the kettle beautifully and is a light green colour meaning you can't accidentally mistake it for water, especially in our glass kettle. It's not quite as strong as the branded stuff, but there's not much in it and or is much cheaper.
This stuff is great for limescale in the loo. We used to use it when we were in the pub trade so were really pleased to find this especially as it's on the Isle Of Wight like us.....what's the chances??!!!!!
If you suffer from limescale you can't do better.
Highly recommend this product.
