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

Excellent item got rid of the limescale build up in a old house a good size bottle, no horrible chemical smell easy to use

sorted out my really stubborn toilet limescale. Previous owners had left the toilet in a bit of a mess nothing cleared it no matter how hard i cleaned it! i left the solution to work overnight then in the morning gave the toilet a good scrub and the limescale just flaked off so easily! the toilet looks brand new :)

Used to descale the kettle tried other tablets but they didn’t work well this fluid worked instantly it did a brilliant job with no fuss or mess I will get the bigger bottle next time

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.

This is brilliant and really works.

Works great definitely buy again super buy

Love this stuff for kettles or any where you have hard water

Excellent descaled a taps tank Would purchase again

You need to use this to believe it. Amazing product.

No suelo poner reseñas porque prefiero darle tiempo al producto para tener una opinión más informada. Me recomendaron éste para quitar la cal (hervidor de agua, cafetera, etc.) y me ha funcionado a las mil maravillas!! No es barato, pero no hace falta usar mucho, definitivamente merece la pena y lo volveré a comprar.

I saw a reviews and thought it’s a calcar killer, well it isn’t. We purchased something with a great calcar and we did the procedure with a product. Calcar still there but then we fought it with enormous amount of bleach. So don’t put too much hope it’s just a decalcar here you just need to pay also for shipping.

Fast delivery of product I have used for 30 years . Excellent for removal of all calcium scale but be aware of safety precautions with an acid based product like this ! !

Ordered it a couple of weeks ago, used it on my bathroom fitting to remove hardwater stains , works great, doesn't need scrubbing or anything, the hard water stains start loosening up in seconds after application of the liquid. Do diulte it and refer instructions before use. The stains just wash away really easily, would recommend wiping off the surface after use as it might leave behind residue after it dries. Overall does what it says and really happy with it. The cost of the product is on the higher side.
