Use URIC XTREME® to clear a urinal blockage.

URIC Xtreme® is a quick, easy and safe to use urinal unblocker - developed for the specific treatment of protein/calcium (uric scale) build-up in ceramic, plastic and stainless steel urinal traps - and the pipework leading from them. It has a unique formula based on phosphoric acid, and has been designed for optimum use as a ‘one dose’ urinal unblocker. URIC Xtreme has no odour and will not give off any harsh fumes. It is therefore both easy and safe to use, and will dissolve any calcium/protein (uric scale) deposits that have led to a blockage. Use URIC Xtreme when the urinal is completely blocked or the flow severely restricted.

Currently used by Network Rail: We have been using uric xtreme for about two years now in both public and employee urinals and blockages are a thing of the past. We have recently started using the alkaline drain unblocker which has proved a remarkable success. I would recommend these products to anyone on industrial or commercial premises as their use has saved a lot in man hours worked. Nigel Chant - Network Rail - 5th June 2019

Watch URIC XTREME® clear a completely clogged urinal.

URIC Xtreme® Product Demo: A mock urinal system packed with uric scale - easily and safely cleared using URIC Xtreme®. The test was set up by the maintenance team at Gatwick Airport. The product demonstration was carried out by Chemassist®.



How to use URIC XTREME.

URIC Xtreme is used neat, and is simply poured into the urinal. Start by pouring approximately 1 litre into the urinal bowl/trough, and wait for this to run away. Repeat after approximately 5 minutes (if necessary) - until the urinal flow is back to normal. No need to flush with water. Normally, a total application of between 1 and 5 litres will be sufficient to unblock a urinal. (Amount needed will depend on the severity of the blockage.)

Please Note: If necessary the urinal trap can be removed and submerged in URIC Xtreme for approximately 10 minutes. The calcium/protein (uric scale) deposits will dissolve very quickly. The urinal trap can then be easily reassembled.

  • Adam Harrison, A&L Cleaning Services 

    I had to buy 4 containers without knowing how reliable it would be. A big spend going on people’s recommendations. However, I used 2 full bottles in 8 urinals and left it over the weekend and it worked. Everything seemed to be running clear on my return. Happy customer.

  • Tim Smith, National Trust 

    Needed to find a product that would not damage our klargester system and Chemassist were very helpful. I use this to treat our urinals once a month and since we have been using this treatment our blockage problems have reduced significantly. Ordering on line is simple and straight forward, delivery is very quick.

  • Andy Summers, Green Air Mechanical and Elect 

    We have tried several other products on the market however none of them close to Uric Extreme. It’s the only chemical that does what it states which is clears urinals! Would recommend to anyone in this field of work looking to unblock and maintain urinals. Safe, easy to use and found to be 100% effective.

    30th Aug 2023


    We were very pleased with the service of your Company and would use your services again. Many thanks.

  • David Warren, St James the Great PCC 

    The whole ordering process was efficient and I got delivery the day following. I initially enquired if it was possible to order a lesser amount, and received a very prompt reply, which included the information I could use the product in maintenance mode. The product was used to clear a blockage and it worked the first time! Very pleased with the result and will use in maintenance mode to keep the urinals clear. Overall I am very satisfied and do not hesitate in recommending the product to others.

    After trying other product unsuccessfully, I ordered this and it cleared the problem pretty much instantly! Highly recommended

    24th Apr 2023


    Excellent product. Cleared blockages from two urinals effectively after I previously tried another product from a different manufacturer that didn’t work. I will now regularly dose all the urinals we have at school to hopefully prevent any future blockages. Highly recommended product. Thank you.

  • Joe, Venue Nightclub  

    Was quoted £1500 to fix our urinals and replace all the pipework, found this online and thought it was worth a go with the guarantee in place. 10L of this and they’re flowing again with no problems with another 10L in storage for any future problems. Would 100% recommend to anyone to give a go if you’ve a blocked urinal.

    20th Jul 2021

  • Sue Bryant, Giffards Primary School 

    We had tried lots of other chemicals over the last few months as well as removing and thoroughly cleaning all of the pipework we could get to (gruesome in the extreme!) to no avail. Then Uric Extreme was recommended to us. It worked the very first time, we only used 3 litres out of the 20 - amazing! The caretaker then poured some into other urinals that were running very slowly and they must have been blocked too as they are now running so much better once more, for the first time in ages. So impressed we have now purchased the maintainer to ensure that all urinals are consistently flowing freely. Ordering was easy, delivery really quick. Thank you!

  • Denise Hook, Zytek Automotive Ltd 

    The service received was outstanding, very helpful and obliging. The goods where dispatched efficiently and received items within a few days. When we had problems with credit card payment, I spoke to a gentlemen who reassured me that the goods would still be dispatched and payment would be sorted there after which it was, but was impressed that the goods was still sent and payment was not a problem. Thank you for your support and understanding. Denise

  • Antony Hooper, Blake Warehouse 

    This product works well. When i had a block before i had to take the panels off to get to the trap. This time i just poured in the chemical and let it do the work. I will use it ongoing to keep it clear.

    26th Apr 2021

  • D.T.Hickliong, British Parachute School

    Had a nice phone call from Steve at Chemassist as I had written about a problem that didn’t quite get solved first time around. He is sending me a slightly different product which should sort the problem FREE of CHARGE!! Now thats what I call Customer Support!! Thanks Steve!

    6th Mar 2020


    Used the product for the first time and to be honest was a bit sceptical, however, having a urinal that was completely blocked, it was clear within 1 hour - far better than anything I have ever tried previously. Fantastic service from Chemassist into the bargain!!!

    13th Feb 2020

  • Julian Keeling, Vindis Group Ltd 

    Painless and helpful service from Chemassist. Purchasing online was really easy and it arrived with the COSHH data sheet. So far the product is just what we’re looking for and has worked a treat. I really hope this proves to be the ’something’ that, at long last, will unblock a urinal quickly and efficiently. So far it has and all is looking good for a far easier future

    21st Jan 2020

  • Paul Hull, Bishop Tufnell Primary school 

    used this in a large primary school where the first floor urinals drain into the same waste as the ground floor ones, blockage somewhere between the two and not able to get rods down due to bends in the pipe work the pipe work was completely blocked not allowing any water to flow, we put the product in at the end of the school day, the next day there was a slight flow, treated again and the blockage cleared, we have used before and would use again

    8th Jan 2020

  • Phil, Bletchley Park 

    First and foremost the service from Chemassist was great. Purchasing online was really easy. COSHH data sheet arrived without request. Product arrived in a very timely manner. The product is just what we’re looking for and worked a treat. It’s so exciting to find something at long last that will unblock a urinal quickly and efficiently. I say exciting because we’ve tried all sorts in the last few years to no avail.

    Fantastic company to deal with 5* service

    11th Nov 2019

    We have used this product before and we will probably use it again, great for the problem areas of reduced flow due to the build up of scale etc

    Great product. Got the urinals flowing fast without having to call a plumber. Have recommended to the plumber now.

    Five Stars!

    21st Oct 2019

  • David Wikllis, Box And Seal 

    Brilliant product, the urinals had stopped flowing completely, I poured in as much has I could before it overflowed, about 1/2ltr into the 2 urinals and left it for about 30mins and I could see that it had started to go down, so I left it a bit longer until I could put at least a litre down and within an hour it was clear. Would definitely reccomend

    21st Oct 2019

  • Jim Nuttall, Shimadzu Research Laboratory  

    Excellent product. Used approx 2 litres and cleared v. slow draining urinal within minutes. No more floods! Used remainder of bottle in three other urinals to ensure they are draining freely. Very good, simple ordering. Will certainly use in future.

    12th Jul 2019

  • Barbara Day, Copperchase Ltd. 

    Contacted this company as we had a problem with our urinal, extremely fast delivery and product worked excellently. Quite an expensive product but you get what you pay for and this did the job perfectly. Definitely recommend supplier and product.

    Excellent. Worked exactly in 10 minutes. All clear now.

    26th Feb 2019

  • Chris Lindesay, Sun Inn Dunsfold Ltd 

    Sorted out our problem very quckly. My only comment is with a minumum order of 20 Litres being delivered in two boxes containing two 5 litre containers and using only 3 litres to resolve the problem. I felt that I now have to store 3 containers for a long time and there is a lot of cost in there. I felt I was being force stocked unecessarily. However I managed to sell half my order on very easily. great product but i wonder about the business model.

    19th Feb 2019

  • Kate,  

    This worked rapidly and gave excellent results. It was easy to use and free from odours. I wish I`d discovered it earlier. The ordering and delivery process was extremely smooth.

    5th Feb 2019

  • Christine Hague, Toutes Directions Limited 

    I can say with confidence that, after researching many Uric solutions on the internet, your website seemed the most easy to follow and as an added bonus it was the cheapest too. Whereas other sites seemed to be sometimes a little vague about their product yours was informative and simple to understand. We placed the order on Friday and called to make sure we had ordered the correct amount. The call was answered by a knowledgeable and friendly chap who reassured we had the correct amount and that it should be with us by Monday. Monday, as promised, the containers arrived and with a little apprehension we followed the easy instructions. Hey presto! We had four unblocked urinals in no time at all, after being completely blocked for a number of weeks! No nasty chemical smells or harmful fumes either. To say we are satisfied with your Uric Xtreme would be an understatement, we are over the moon! Thank you so much!

    21st Jan 2019

  • Derek Morris, Hogarths Hotel 

    Excellent product, dealt with a very difficult blockage issue as described in the product write up, would definitely recommend.

    first class product, used on two blocked urinals , one on the first floor and one on the ground floor, the waste pipe between the two completely blocked, we put the product down the the pipe and left overnight , the next morning it was completely clear, quick delivery, a bit expensive but far cheaper then paying for a drain clearing company to come on site
