Harpic 100% Limescale Remover Original, 750ml

Works brilliantly on limescale in our hard water area. Apply it under the rim so it runs down the pan getting into the limescale you can't see. Then a good squeeze into the water in the bowl. I leave it for at least 2 to 3 hours. But if going out all day apply it before you go and leave it all day, the longer you can leave it the better it works. Keep the lid down to stop any unwanted pet visits, or to stop young children playing. It is a bright blue colour but I dont know if they do a clear or white coloured liquid?

Without any doubt on this earth, this is way better than any "bleach" or "toilet cleaner" or "limescale remover" all rolled into 1. People try to claim that coke works if you pour 2 litres in and leave it. Nope. My toilet had a "lazy flush" due to a new part needed for the toilet, and the fact that I live in Suffolk! The dirtiest water in the UK bar London I'd say. So if you have a humidifier, use RO water or your entire room will have a fine layer of white dust over it. That is the dirt they put into the water to "clean" in or to keep the people who drink it subservient. We all know the fluoride thing was a lie. It was used in much higher doses in the death camps, and it's also used more in prisons where they attempt to kill any testosterone off. So luckily this stuff exists. Because after buying expensive "limescale" treatments, I stumbled upon this at the very reasonable price. And it gets the utter jank off whatever you you use it for. Obviously it doesn't aide in your drinking water unfortunately. But I won't drink tap water in Suffolk as it's disgusting. You can smell the chorine and bleach and god knows what else they use to "clean" water. I have triple water filter for coffee or drinking. If you have the same issues as me, you'll know this stuff is amazing! I was then ordering more when I found a cheeky full bottle in with the used ones. Set that straight to work, and the toilet (even the parts your brush won't reach) will be limescale free. I will only use this stuff from now on. And I wish I'd found this before all the other rubbish!

Living in London means lime scale, that includes the loos too, this removes it effectively and leaves them clean and sparkling. I use other products on a daily basis to be more green but this once a week over night and that seems to be enough.

Does the job, however cheap bleach from Aldi or Lidl seems to clean better. Happy with the bull putchase. Not sure if I would buy again due to the cleaning side as bleach cleans better.

I bought the multiple box of bottles in order to go halves with nearby neighbours. I desperately needed to treat 3 of their loos that are from the 1960s ,1970s and 1980s, (the house of the elderly couple), they had been using bleach, but the loos were completely coated in thick brown limescale. One loo (Late 1970s Pink) the told me that the glaze has gone/damaged near to U-bend, so they were not bothered if any other damage was caused. I'm happy to say that all is well and the worn glaze actually might be mostly limescale, I can see that gorgeous (not) glazed-colour. So far with two applications, spaced apart by around 3 hours, and I could finally see the Pink, White and Cream toilet bowls, It didn't quite work enough under the water-line. I have now had to completely get rid of the water at the bottom, and giving it another chance to do its magic, as it dissolve the rest of the limescale I hope. There are still a few stubborn stains, which I think will go by the end of the week, and by using a stiff loo brush is helping. The smell on first application was a bit unpleasant, almost like boggy gassy (yes gassy not grassy) marshland, on the 2nd time it was not so bad, it sort of smells like what they used to use at the old Railway Stations and Public loos back last century, otherwise it is not too bad. I will be using it at home, now too.

This is the best cleaner so far. It doesn't bleach fabrics either. It turns you bathroom from yellow and scaly to white gleaming clean. I love this stuff I cannot go without it. The price I got at too was just perfect for me as it was on offerr. The tip makes it easy to use in the toilet bowel as it reaches those hidden corners. And really good for corners and tiles in the shower area.

For best results, squirt up all around the toilet rim in the morning, squeezing the bottle hard and using most of it, to fully curtain coat the bowl and allow to run down into the bottom/U bend and leave until you return from work in the afternoon/evening then scrub the bowl with your brush before flushing clean. No need to drain the bowl before application as this amazing gel even works under water. Can be spread around sinks and shower trays and poured over chromed taps and overflow caps to dissolve years of accumulated limescale that Viakal requires multiple applications to remove. Unless you bought your toilet from brand spanking new, you've probably never seen it this clean!

Good product

Its a good product but be careful not to bring any metal surfaces like tap or metal hose in contact with it.else they may get a stain

This product is totally ineffective. It didn't remove any limescale despite applying it several times. It's an useless product and waste of money.

This product is good for cleaning of sanitary ware. However, this is not for removing scales. This is not at all removing scales. The consistency is lesser compared to usual Harpic cleaner. The consistency could be increased so that better results could be achieved. The price is also on higher side.

Product is good and nice packing… product works fine… worth for money…
