Kilrock Gel Descaler 160 Grams - Multi-Purpose Powerful Descaling Cleaner with Easy-to-Use Brush Cap - for Hard Water Limescale Stains

This stuff is amazing. When we moved in there was years of limescale on the shower cubicle which wouldn't come off and continued to build. I bought this on the off chance. Painted it on and left for 6 minutes and it literally just wiped away with a damp cloth. It also worked on taps as welivein a very hard water area. Cannot recommend this highly enough.

This Limescale remover is so powerful! It does the job well and very quickly. The smell can be strong, so beware of that.

This has got rid of horrid limescale in my sink. I have tried bicarbonate of soda, vinegar, bleach etc etc but nothing worked. This product is easy to use with a brush attached to the lid. However, I had to use it 4 times, leaving for a few hours each time to completely remove the limescale. I would recommend it as it does do the job.

Like the applicator on this for things that can’t be removed. Works well.

Years ago when I used to work with a friend who was a cleaner she introduced me to this product. It worked just brilliantly especially on taps, plug and plug holes and the edge of the overflow. She always had a pot on hand and I eventually went out and bought my own for our home. Limescale (just hate the stuff) and it builds up before you know it so always upkeep the basins and taps now. I hadn't used this product for a few years because we had moved and the area we are now in doesn't have as much of a limescale problem. However we changed some taps and the hubby wanted to thoroughly clean them before replacing so I purchased this product knowing how well it worked. I have to say I was a bit disappointed. It works nowhere as well as it used to, I remember you would simply 'paint' it on using the brush in the lid and it used to foam/fizz on the limescale which you then left for a few minutes to do its thing and come back to wipe away. Well, it didn't do its fizzing magic at all and somewhat removed some tough limescale but just not fully. Bit of a let down. Either I got a faulty product or its not the same as it used to be.

Excellent product, removal of scale

This stuff is amazing. I’d tried a branded one and it didn’t make a difference but this really works. It took about 4 goes to get caked-on limescale off a black shower trap and one go to get the yellow streaks off porcelain and with only a toothbrush. I left it on for 20 mins. Highly recommend

Worked brilliantly. Didn't take long for lime scale on vertical surface to disappear. Best to use with door or window open.
