“Works well! Live in a hard water area so lots of limescale. Used as directed in kettle
and now it’s sparkling clean.”

“Brilliant product! Bought this on offer from Ocado and used it for the first time. So glad I did! It left me kettle looking as good as new and, instead of throwing the water away, I used it to clean my kitchen sink which had lots of limescale marks. What a stunning shining sink I now have! Very pleased with the results on both my kettle and sink so I am stocking up!”
