| Product | Why It Fails | | --- | --- | | Bleach | Bleach is alkaline. It reacts with ammonia in urine to create toxic chloramine gas. It does not dissolve crystals. | | Ammonia-based cleaners | These add more alkalinity, making crystals harder. | | Boiling water | Can crack porcelain urinals due to thermal shock. | | Hard scrub brushes | Only remove surface dust; they cannot penetrate hardened crystal layers. |
Sometimes crystals form a solid plug in the trapway (the curved pipe below the urinal). If chemical treatments fail:
Citric acid is a mild, food-safe acid that outperforms vinegar. Buy powdered citric acid (canning supply or online).
For facility managers or anyone dealing with heavy buildup, commercial uric acid removers are the fastest solution. Look for products containing sulfamic acid, hydroxyacetic acid, or phosphoric acid.
Step-by-step:
Safety: Always wear rubber gloves and goggles. Acids can cause skin burns. Ensure the room is ventilated.
For a standard commercial urinal with a slow drain, buy a bottle of Sulfamic acid crystals (often sold as "Urinal Descaler"). Mix with warm water, pour, and wait. It costs $15 and saves you a $300 plumbing bill.
When to call a plumber: If you pour acid, wait 12 hours, and the water still doesn't move, the crystals have likely traveled past the trap into the cast iron waste pipe. That requires a professional hydro-jetting.

because traditional soaps and detergents are ineffective at breaking down these hardened mineral deposits. Citron Hygiene Effective Methods to Dissolve Crystals Choose a method based on the severity of the buildup: Enzyme-Based Cleaners (Best for general use):
These biological cleaners contain living organisms that "digest" the uric acid crystals and destroy odor-causing bacteria. How to use:
Blot up any standing urine first. Saturate the affected area with the cleaner and let it sit for at least 10 minutes. For old, dried deposits, cover the area with plastic wrap for 24–48 hours to keep it moist and active. Commercial Descalers (Best for slow drains):
For blockages deep in the "p-trap," use heavy-duty descalers like Javelin Urinal Treatment How to use:
Pour roughly 16 oz (or as directed) into the urinal and allow it to sit overnight before flushing several times in the morning. Acidic Home Remedies (Best for minor scaling):
Pour roughly 250ml of white vinegar into the urinal container or drain and leave it to work overnight. Citric Acid:
A gentler alternative to vinegar that is effective for minor scaling but may struggle with stubborn, thick deposits. Baking Soda & Vinegar:
Mix 1 cup of vinegar with 1 cup of baking soda for a fizzing action that can help loosen surface stains. Citron Hygiene Specialized Product Options

Urinal Cleaning: How to Get Rid Of Uric Scale & Smell in Toilets
To dissolve urine crystals (uric scale) in urinals, you should use specialized enzymatic cleaners or acid-based descalers, as standard soaps and detergents are ineffective. These crystals form when urine reacts with oxygen and minerals in flush water, creating a hard, alkaline substance that clings to porcelain and pipes. Step-by-Step Dissolving Process
