Urinal unblocker & descaler for blocked traps & pipework
URIC XTREME® by ChemAssist® is a professional-grade urinal unblocker and descaler, developed for the specific treatment of protein and calcium (uric scale) build-up in ceramic, plastic and stainless steel urinal traps - and the pipework leading from them. Based on a unique phosphoric-acid formula, it is designed as a one-dose urinal unblocker that dissolves uric scale quickly and safely. It has no odour, gives off no harsh fumes, and contains no sulphuric or hydrochloric acid - so washrooms do not need to be closed during use. Use URIC XTREME® whenever a commercial urinal is completely blocked or the flow is severely restricted.
URIC XTREME® is a urinal unblocker and descaler that works inside the trap and pipework - dissolving the uric scale that causes blockages, not just surface deposits. Hard water and proteins in urine combine to form hard uric scale, which accumulates in urinal traps and pipework until it restricts or completely blocks the flow. As both a urinal unblocker and a urinal descaler, URIC XTREME® rapidly breaks that uric scale down at source - clearing the blockage and descaling the trap and pipework in a single application. It is the commercial urinal cleaner trusted by facilities teams, contract cleaners and washroom managers across the UK.

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.

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 to unblock a urinal
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.
Pour URIC XTREME directly into the blocked urinal so it reaches the trap and pipework. Its phosphoric-acid formula dissolves the uric scale causing the blockage, usually within minutes. For a completely blocked trap, remove as much standing water as possible first so the product can reach the deposit, then flush through once the blockage clears. No plunger, rods or plumber required.
The most effective urinal unblockers are phosphoric-acid based, like URIC XTREME. Phosphoric acid dissolves the uric scale (calcium and protein deposits) that cause urinal blockages without the danger of sulphuric or hydrochloric acid, and without damaging ceramics, stainless steel, plastics or pipework. Caustic (alkaline) products are designed for organic drain blockages, not uric scale, so they are far less effective in urinals.
Uric scale is a hard calcium-and-protein deposit, so it needs an acidic descaler to dissolve it. Dose URIC XTREME into the urinal and leave it to work - it breaks the crystals down at source in the trap and pipework. For heavy build-up, a second application clears anything remaining deeper in the pipe. Regular dosing with a maintenance product such as URIC FREEFLO then prevents the scale from reforming.
Yes. For waterless or waterfree cartridge urinals, remove the cartridge first and apply the product directly into the drain or pipework so it bypasses the cartridge. It is safe on the plastics and ceramics used in waterless systems and dissolves only the uric scale and deposits causing the blockage.
No. URIC XTREME is safe on ceramic, stainless steel and plastic, and on copper and plastic pipework. It contains no sulphuric or hydrochloric acid, is non-caustic, and dissolves only the uric scale - so it cannot be overused and will not harm your urinals or drainage.
It typically starts dissolving uric scale within minutes. Leave it in contact with the blockage for the time stated on the label, then flush through. Stubborn or deep blockages where the pipe is full of liquid may take longer or need a second dose.

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

Easy to order, quick delivery and although it took a few days of application it finally cleared a full blockage without any need to remove pipework etc. Will use now periodically to maintain clean pipes.

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.
