How to Remove Deposits in a Urinal

Uric acid crystals are the solid residue of urine that collect on the inside of urinals, and they can be very difficult to remove. Traditional cleaning products such as soaps and strong detergents are ineffective at breaking down these crystals. The best choice for removing these deposits from a urinal is an enzyme-based cleaner specifically designed to bind to and break down the uric acid crystals, while also destroying the odor-causing bacteria around the crystals. You can find this kind of cleaner online or in janitorial supply stores.

Removing Fresh Urine Deposits

    Soak up as much urine from the urinal as possible by blotting with paper towels.

    Soak the affected area with an enzyme-based cleaner.

    Remove residue, after urine odor and stain are removed, by blotting with a damp paper towel.

Removing Old Dried Urine Deposits

    Saturate the area with enzyme-based cleanser.

    Cover with plastic wrap for 24 to 48 hours, allowing the product to stay moist and effective longer.

    Allow to air dry. If the stain is still visible after air drying, repeat Steps 1 and 2 until the deposits are gone.

    Remove residue by blotting with a damp paper towel.

    Tips

    • Wear rubber gloves when working in urinals or toilets.
