: Use specialized dome screens embedded with slow-release biological blocks that continuously deposit scale-inhibiting enzymes into the trap with every flush.
: Place specialized enzyme or descaling blocks inside the urinal screen. Every flush releases active ingredients that inhibit crystal formation.
For , the process is slower. These often need to sit overnight or for several hours to fully digest the buildup. 5. Agitate and Flush
For severe, stone-hard blockages, professional plumbers rely on inhibited muriatic (hydrochloric) acid. Standard muriatic acid can destroy your metal pipes, but "inhibited" formulas contain special additives that protect the plumbing metal while aggressively dissolving the uric scale. how to dissolve urine crystals in urinals
: Flush the urinal multiple times in the morning to wash away the dissolved residue and remaining chemicals. Citron Hygiene Prevention Tips Crete, Heavy Duty Urinal Descaler and Odor Treatment
Urine crystals, also known as uric acid crystals or scale, form a hard, rock-like buildup inside urinal traps and drainpipes. If left untreated, they restrict water flow, cause complete blockages, and trap foul odors that no amount of air freshener can mask.
If you need help tailoring this process to your specific facility, please let me know: : Use specialized dome screens embedded with slow-release
This is the most recommended modern solution. These cleaners use beneficial bacteria or enzymes to biologically "digest" the uric acid and organic waste. They are highly effective for without any harsh chemicals.
Standard soaps and detergents are ineffective against hardened uric scale. Use one of the following specialized types:
: Let the chemical sit undisturbed for 15 to 30 minutes to break down the crystallization. For , the process is slower
Waterless urinals are highly susceptible to scale because there is no water to dilute the uric acid. If you use waterless systems, they must be flushed manually with a bucket of water weekly. For standard urinals, ensure the auto-flush sensors are operating correctly and providing enough water volume to clear the p-trap completely.
For small, surface-level stains or if you prefer an eco-friendly approach, household items can be mildly effective. However, they are not powerful enough for serious blockages.
