Kilrock Mega-K Multi-Purpose Descaler 1 Litre (12 Doses) - Limescale Descaling for Kettles, Shower Heads & Coffee Machines - Biodegradable and Phosphate Free

Kilrock Mega-K is hands down the best descaler I’ve used. It works quickly and effectively on everything from my kettle and shower head to my coffee machine. After just one treatment, my appliances looked and worked like new again!What I really appreciate is how powerful it is without being packed full of harsh chemicals—it's biodegradable and phosphate-free, which gives me peace of mind when using it at home. The 1-litre bottle lasts a long time too, with 12 doses per bottle, making it great value.It’s easy to use, and the results are impressive. Highly recommended for anyone dealing with hard water and limescale build-up!

Amazing product, used it for several things. It removed all limescale from my kettle as if it's new now.Also used it for the toilet, all the stuck brown is gone, soaked over night (did it twice) keeps everything shining and super clean!. Easy to use.Make sure you wear gloves. Also, has a very strong smell.Does not Leake.

This is great for descaling your kettle and kitchen/bathroom taps etc. with it being a 1 litre bottle size, it is really good value. Highly recommended

Ok, I did receive a leaking bottle of this stuff but Amazon dealt with this issue in their usual, efficient way. There was enough of the liquid left to try, however. So the question is: does it work? Well, yes it does, on some limescale. Let me be more specific. I have some taps that have become enveloped by crusty deposits of limescale. I painted the liquid on the taps with an old paint brush and left for an hour or so. Some of the deposits came off after wiping with a cloth, so I reapplied. A bit more came off, but there are still deposits left which are resistant to even my scrubbing with a hard toothbrush. I might try again, but I suspect this is as good as it gets. It seems to perform better on kettles, coffee machines and other appliances. Now, I’ve used all different kinds of limescale removers and I can’t honestly say that this has performed significantly better than less caustic formulas. Indeed, I found the stench on this stuff pretty unbearable. So much so I had to wear a face mask whilst I was applying the liquid to the taps. Admittedly, though, there is little ventilation in my small upstairs bathroom. But do take care if you are using this. A mask and gloves are a good precaution. Keep kids and pets away from areas where this is applied and wipe down thoroughly afterwards with soap and water or antibacterial spray. If your limescale is more of a mild irritant than a major problem, use something more environmentally friendly and plant based. Only use this as a last resort, it really is quite toxic if used incorrectly.

Good stuff, cleans the hard scale out of kettle, very effective. Strong smells when using so i put the stuff in kettle outside, too strong of a smell do use indoors. Great product cleans and gets rig of hard scale.

This is an exceptional product. After trying with different products and failing to remove very old and strong limescale around a leaking kitchen tap, including on quartz kitchen countertop, I used this product and it worked wonders! 100% recommended!

Superb product, always gets the job done.

Best descaler ever works really well and you don’t have to use much i never use the recommended amount.
