How to get rid of urine odours in urinals
Urine odours from urinals can come from two sources:
Firstly, the urine that misses the urinal & ends up on the floor, wall, grout, tiles and the surrounds of the porcelain or stainless steel bowl. Secondly, the urine in the urinal bowl and uric acid crystal build up in the S-bend of the pipe.
When urine dries it crystallises. It is the uric acid crystals that are the source of the odour, that gets embedded into both hard and soft surfaces. Conventional cleaners can remove the urea and urochrome components of urine because they are water soluble but will leave behind the non-soluble uric acid crystals that can only be removed using a bio-enyzmatic product such as urineFREE®. Any moisture or heat will reactivate these crystals and the odour returns.
The first odour source, outside the bowl, is easily eliminated by using urineFREE. Saturate the affected area with urineFREE. Allow to air dry and once dry, rinse with water to wash away the residue from the biological activity. We suggest two to three treatments in succession to eliminate the accumulated urine build-up and then regular maintenance as required.
The second source of urine odours, the bowl and S-bend of the pipe, will take a little more effort. There are two types of urinals we see in the market today, water-flushing and waterless. Both are susceptible to uric acid crystal build-up
With the water-flushing urinal, the uric acid crystals get lodged in the S-bend and can result in the bowl overflowing. If you ran a camera through the pipe you would see a solidified ball of uric acid crystals. When the urinals are not in use, the urine odour can escape and will activate with urination.
Instructions: To solve this problem, when the urinals are not in service, turn off the water and saturate the uric acid crystals in the s-bend with urineFREE. To “eat” these large number of crystals will take some time and several treatments but eventually they will be eliminated. If the urinals are flooding and you can’t wait for the treatment to work, call in the plumber. After the plumber clears the line, commence using urineFREE to avoid a recurrence.
With the waterless urinal, most of them, but not all, use a sealant that is lighter than water and the urine passes through the sealant and the sealant prevents the odours from escaping. Some waterless urinals have a cartridge (a trap) that urine flows through and into the sewer line. If the sealant is not topped up periodically and the cartridge is not cleaned regularly of uric acid crystal build-up, the urine odours will return.
Instructions: The solution is to saturate the bowl and cartridge with urineFREE to prevent the uric acid build-up on the cartridge and then make it an ongoing part of your urinal maintenance program.
