KilrockBig K Multi-Purpose Descaler 400ml (5 Doses) - Limescale Descaling for Kettles, Shower Heads & Coffee Machines - Biodegradable and Phosphate Free - 100% Limecale Removal

Leaves the kettle spotlessly clean inside. We live in a very hard water area and *everything* gets scaled up. A lot of products claim to remove limescale but don't really seem to do anything (mostly toilet bowl products to be fair). After boiling this up in the kettle I dump it down the toilet and it has enough strength left (leaving it overnight) to get rid of the limescale build-up under the water level.Not the cheapest, but if you use it every couple of months it will definitely stop your kettle (and toilet) looking gross.

This is a great product! i've used other brands over the years but this seem to do a far better job. gives a great looking clean it not sticky as such and there's no strong chemical smell to it .

Used this on the kettle and it took all the limescale off leaving it as good as new.Easy to use simple instructions works a treat recommended

Very effective in dealing with limescale but if you have a sensitive nose, be aware! This really catches in the back of your throat, and it made my eyes water a bit, so stand well back when using it. It doesn’t take long though, in the kettle, and left it all sparkling. I didn’t use as much as suggested as otherwise this bottle won’t last long, but it’s an excellent part of my cleaning kit. Good on taps too, wipe over, leave then rinse off.It’s a bit more pricey than buying one off sachets but if you don’t use quite as much each time, it’ll last and it really does work.

Very good product does the job. Happy to recomm

Brilliant descaler.Very nice size bottle.Very fast delivery very well packed.I would recommend.Thank you

Best descaler I have used and always buy it now! Great price. Cleans my kettle perfectly. Quick and easy to use.

Does exactly what it says… strong smell… but never failed to leave kettles gleaming
