Ben Walker is a well-known and very respected cleaning consultant. He and his company, Management, Inc., work with large facilities and contract cleaning companies all over the world, helping them streamline cleaning operations, improve efficiencies, and reduce cleaning-related costs.
A few years back, his company was hired to help streamline cleaning operations for a new, exceptionally large, state-of-the-art building in San Diego, CA.
As he was touring the facility for the first time, he noticed something in the restrooms he had never seen before: waterless urinals. He was told they were installed because they can help reduce water consumption dramatically, as much as 35,000 gallons (about 132489.35 L) of water per year per urinal. In thirsty California, as well as many other western states, waterless urinals are now commonplace. In 2006, not so much.
Walker says that as far as cleaning and maintenance in the new building, everything was going perfectly – at least initially. The client was happy as were the building’s tenants. But by the third month, problems developed. The waterless urinals that the building proudly installed were releasing pungent odors that could be sniffed throughout the facility.
“This was a problem I had never faced before,” says Walker. And it was not just Walker. “I found…the custodial crew members [were also] struggling to keep the new waterless urinals clean, but a very pungent odor was beginning to overtake the facility.”
What Walker later found out was that while waterless urinals offer “huge benefits,” as he called them, allowing organizations to meet their sustainably needs, they have their own cleaning requirements, many of which differ from the ways traditional, water using urinals are cleaned.
"While the cleaning procedure for waterless urinals isn’t difficult, they have additional process that managers need to be aware of.”
Now aware of this, among his suggestions to managers and cleaning professionals are the following:
Read the cleaning instructions. Most manufacturers provide cleaning instructions with the waterless urinals. All too often, no one reads those instructions until a problem arises. Those problems usually can be eliminated if the instructions are read before any cleaning is performed.
Make sure the staff is using the proper cleaning solutions recommended by the manufacturer and that the chemicals are diluted properly. Some brands may require specific cleaning solutions; however, most waterless urinals can be cleaned using traditional cleaning solutions such as all-purpose cleaners, sanitizers, and disinfectants.
Keep the cleaning solutions from draining into the cartridge at the bottom of the urinal. The cartridge serves an especially important function. It helps prevent sewer odors – such as those this building in San Diego was having – from escaping into the building. If the cleaning solution fills the cartridge, it could reduce its effectiveness. To prevent this from happening, remove the cartridge when cleaning. (NOTE: This is Walker’s advice. This may not be necessary with all waterless urinals).
Wipe the urinal cleaning from the down. Also, use a cotton cloth or microfiber towel. Some cleaning professionals use paper towels. Paper towels are good for drying hands but not effective in cleaning, including cleaning waterless urinals.
Finally, take note as to when the cartridge was installed. Some cartridges have a noticeably short lifespan, two or three months.
Our comment: Interestingly, these short-lived cartridges are often the most expensive. The cartridges installed in urinals manufactured by Waterless Co., Inc, are inexpensive and can last as long as six months. Further, waterless urinals from Waterless Co., come with a unique key that can be used to quickly remove the cartridge when it needs to be changed.
Finally, determining when the cartridge needs to be changed can be subjective. Cleaning professionals should conduct a sniff test every time they clean a restroom where waterless urinals are installed. After two to six months, depending on what type of cartridge is installed, an odor may become noticeable. That means it is time to change the cartridges. Have more cartridges in the supply cabinet to remove the old unit and install a new one, in seconds.
