Kilrock Big K Multi-Purpose Descaler 2x400ml (10 Doses) - Limescale Descaling for Kettles, Shower Heads & Coffee Machines - Biodegradable and Phosphate Free - 100% Limecale Removal

Have used the product before to descale a heavily scaled kettle. It works very quickly and effectively so have bought again for another purpose.

Great product always works .never fails .

Used on our pro boil 2x hot tap, worked a treat and nice and clean now! Only used a bottle so have another left for the next time!

This is a good product for descaling kettles and small appliances. I have been using it for years, in addition to the kettle etc. I use it for the water tank on my CPAP machine which needs descaling every now and again. It is very effective.It is very important to follow the warnings and instructions carefully. I always put the item being descaled in the sink so if there is spillage it can be flushed away and you are less likely to be splashed in the first place. This product will dissolve delicate surfaces like marble.Wear rubber gloves and make sure the area is well ventilated as the gas from the reaction will make you catch your breath, it is quite unpleasant.Be warned when you pour the liquid into a half full boiled kettle it will foam up very rapidly and will probably come over the top of the kettle.A better packaging system for dispensing the right amount of product would help, say like those used for the dispensing of garden chemicals, so four stars but I do recommend this product to the careful user.AJC

Best multi purpose descaler for household. Super strong, and effective. Work well with scales around taps or drainings, toilets or just with your kettle.Very good price and the best compare to other products.

Best descaler ever.

OMG this product is soo strong.It was recommended to me by a plumber and it has cleared everything!!!Wear a mask due to fumes and thick rubber gloves. keep your kids and animals away or they will suffer.

This was recommended to me by a friend. Used it to unblock a coffee machine that had stopped working even after using the manufacturers own very expensive descaling substance.It worked fantasticly and the coffee machine is now back working as well as when new.
