Kilrock Big K Multi-Purpose Descaler 400ml (5)

These are great. If you keep up the descaling you only need to use a very small amount of solution, even less that what they recommend. If limescale builds up then it’s one of the strongest you can get to remove it.Smell, don’t inhale

Wouldn't use any other kettle descaler . I've tried many, but discovered this years ago & never looked back. Removes all limescale (I'm in an extremely hard water area) - fast & ultra effective. I have a Quiet Boil kettle that only works quietly if the kettle remains scale-free. I descale every time my filter jug cartridge needs changing, which serves as a timely reminder.While I wouldn't recommend getting close & inhaling the fumes, ithe smell is way less noxious than other brands. The lines to mark out the dosage discourages over-dosing, so makes for great value.

This removes limescale effectively in one go. However in case of heavily scaled kettles may take 2-3 go's to get a shiny clean. Ideal for people living in hard water areas. Bit pricey if bought as a single bottle and thus 4 stars. Otherwise quite satisfied with the product bought in bulk as it was much cheaper than buying one bottle.

Perfect for descaling household products - it is the only one I find works well in a hard limescale area like mine. I always use Kilrock descaler for kettle, shower heads etc.

Second purchase of this descaling liquid. Tried many others, but this easily beats them all. Bought their gel version to use on taps, works just as well. This is so easy to use, and quick to do a brilliant job. Strong fumes when in use, and when you open the bottle, so don’t plan on taking a whiff!

Easy to use really good.

An effective product, well packaged and promptly and correctly delivered. Everything I hope for from an online order.

The best discaler for kettles it removes lime scale.
