Ingredients Dezcal P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); Box Contains 1 x 1 litre of bottle of Liquid Dezcal Descaler See more Review: Fantastic descaler, bought for ProBoil3 water tank, amazing on kettle too. - This was purchased specifically to descale a ProBoil 3-in-1 hot water tap water tank, which automatically shuts down when needing to be descaled. It’s out of warranty now ,and the manufacturers own descaler was out of stock for quite some time. To preserve the ProBoil warranty, they say to use their descaler, and one 200ml bottle of their premixed solution costs more than the cost of this concentrated Urnex Dezcal liquid. The manufacturers solution is made using the Urnex Dezcal liquid, so I was delighted to find the concentrate on desertcart. We have very hard water and have previously used 2 bottles of the manufacturers solution for one descale. The Dezcal needs to be diluted with water, one part Dezcal to 10 parts water, and you need to wear protective gloves and goggles whilst handling it, and to ventilate the room. The Urnex website provides all the details on how to use it and what it can be used on. I will certainly stick to using this for all my future descaling of my ProBoil 3, and kettle. I think it should also be ok to clean my coffee machine too, although Urnex do have a range of products to also clean coffee machines and milk frothers. Our ProBoil manual suggests the unit needs to be on and water temperature at 80 degrees when adding the descaler. Ours just switches off so the water in the boiler tank cools down, and it will not turn back on until descaled. The unit stopped working a couple of months ago so we reverted to using a kettle, which also showed signs of limescale build up. With the boiler switched off, I drained off some of the now cold water from the bottom tap using the drain hose, then re closed the tap. I made up a 400ml water/ 40ml Dezcal solution, disconnected the cooled vent hose and slowly poured most of the mixture into the boiler tank. The Dezcal solution must not be left in the unit or kettle for more than 30 minutes. I was concerned that the water in the tank was cold so maybe this would not work. Around 30 minutes reconnect the vent hose, then drain the unit into a bowl by opening the bottom tap connected to the drain hose. Reclose the bottom tap once unit is drained, switch boiler back on and allow to refill and reheat to 80 degrees. When switched back on, the boiler came back to life. At this point, drain the water from the tank using the hot key, so the water drains out via the kitchen tap. Switch the boiler back off, and again drain remaining water from the unit’s bottom tap through the drain hose into a bowl. Close the drain tap, and store the hose away. Switch boiler back on and allow it to refill and reheat, then drain the boiler again using the hot key so that the water flows out of the kitchen tap. It is suggested the unit is drained twice, but I did it 3 times. The boiler is now happily working again, and I have plenty of the Dezcal concentrate for future descaling. I used up the remaining made-up solution by pouring it into an empty kettle and leaving it for 30 minutes. They do say to ventilate the room when descaling, as some odour may be given off. You could see the limescale immediately lift of the base of the kettle and start to dissolve, and the kettle looked completely clean inside after the descale. Empty the kettle, then fill and boil the kettle a couple of times to rinse out the descaler solution before reuse. This stuff is fantastic! Review: Great for Boiling Water Tap Boilers! - Really powerful scale remover with saved for Boiling Water Tap boiler from limescale and subsequent E8 error. Poured in with a funnel mixed as per instruction with warm water and i could hear it fizzing away in the tank. I repeated 3 times emptying out about 1 kg of scale each time. Recommend this for boilers or other household items. ## Features - Causes serious eye irritation. - Causes skin irritation. - For use with coffee brewers, espresso machines, pod machines, capsule machines, kettles - Dezcal is also available in powder and tablet form - EASY TO USE - This is a liquid descaler that is easy to portion to descale commercial boilers and household coffee machines using the included dosing cap ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004NRZ6F0 | | ASIN | B004NRZ6F0 | | Best Sellers Rank | 301,271 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 223 in Coffee Machine Descalers | | Brand | Urnex | | Customer Reviews | 4.5 4.5 out of 5 stars (1,093) | | Customer reviews | 4.5 4.5 out of 5 stars (1,093) | | Date First Available | 10 Sept. 2012 | | Format | Liquid | | Is discontinued by manufacturer | No | | Item model number | 15-DLQ1 | | Manufacturer | Urnex | | Product Dimensions | 8 x 8 x 23.11 cm; 1.1 kg | | Product Name | Descaler | | Units | 1000.0 millilitre | | Volume | 1 Litres | | Weight | 1.09 kg | ## Product Details - **Brand:** Urnex - **Contains liquid contents:** Yes - **Item form:** Liquid - **Item volume:** 1 Litres - **Item weight:** 1.1 Kilograms - **Material feature:** Biodegradable - **Number of items:** 1 - **Special feature:** Biodegradable, Descaler, Non Toxic - **Surface recommendation:** Plastic - **Unit count:** 1000.0 millilitre ## Images ![Urnex Dezcal Activated Scale Remover Liquid Concentrate 1Ltr - Image 1](https://m.media-amazon.com/images/I/71NqUb2hVhL.jpg) ## Questions & Answers **Q: Cani use this in a Bibo Water filter&boiler.I have to leave their brand in 4, 8 hours, but this says 30 minutes.Which is best?Will it b ok 4 bibo?

Can anyone advise please?** A: Instructions: For use on Commercial Boilers and Heating Elements of Coffee and Espresso Equipment Create a solution using 50ml Liquid Dezcal in 500ml hot water. For other volumes, use 1:10 ratio of Liquid Dezcal to water Add solution to water reservoir Hold solution in vessel for up to 30 minutes Rinse all parts thoroughly TIP: Liquid Dezcal is suitable for use by both professional technicians and home users alike. When used on commercial and "closed system" brewers (with a holding tank), special attention should be paid to rinsing. Hope this helps Regards **Q: can one use this descaler on a Jura Espresso Machine ?** A: Hi yes this can be used on a Jura Espresso machine.

Worked as described. Took a star off as the measuring cup which was on top of the lid came broken, unlikely to have been dispatched like that so must have happened in transit ## Frequently Bought Together - Urnex Liquid Dezcal Activated Descaling Solution - 33.6 Ounce (8 Uses) - For Use With Keurig 1.0/2.0, Home Coffee and Espresso Machines, Kettles, Garment Steamers - Urnex Espresso Machine Cleaning Powder - 566 grams - Cafiza Professional Espresso Machine Cleaner - Urnex Grindz Professional Coffee Grinder Cleaning Tablets - 430 Grams - All Natural Food Safe Gluten Free - Cleans Burr and Casing - Help Extend Life of Your Grinder --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/49675756-urnex-dezcal-activated-scale-remover-liquid-concentrate-1ltr](https://www.desertcart.be/products/49675756-urnex-dezcal-activated-scale-remover-liquid-concentrate-1ltr) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-22*
