Cleaning Mobile Public Toilets

Cleaning mobile public toilets requires a systematic process that combines daily maintenance with professional operational standards. The specific steps are as follows:

I. Daily Cleaning (Eight-Step Cleaning Method)

1. Dust and Scale Removal

   • Use a broom to remove dust and cobwebs from the ceiling, walls, window screens, and lighting fixtures to prevent dust pollution.
   • Use a long-handled brush dipped in a non-ionic surfactant cleaner to scrub the alkaline scale in squat toilets, sit toilets, and urinals, focusing on calcified stains.

2. Surface Wiping and Garbage Disposal

   • Wipe high-frequency contact areas such as doors, windows, sinks, and partition boards with a cloth to ensure no water or stain residues remain.
   • Sweep garbage from both inside and outside areas, and promptly replace the sealed bags in garbage bins to prevent odor diffusion.

3. Floor Treatment and Facility Inspection

   • Use a mop to remove standing water from the floor, keeping it dry to reduce the risk of slipping.
   • Check whether faucets, sensors, coat hooks, etc., are intact. Damaged parts should be recorded and reported for repair.

4. Disinfection and Deodorization

   • Spray a dedicated disinfectant on door and window handles, faucets, etc., at least three times a day, with a contact time of 10-15 minutes.
   • Turn on deodorization equipment or light incense to neutralize odors such as ammonia and hydrogen sulfide.

5. Tool Return

   • Store cleaning supplies such as mops and brooms in the tool room to avoid clutter affecting use.

II. Professional Deep Cleaning

1. Pre-Operation Preparation

   • Wear a waterproof apron, non-slip rubber boots, nitrile gloves, and goggles, and set up mobile warning signs to isolate the work area.
   • Prepare high-power vacuum sewage suction trucks, high-pressure cleaners, long-handled hard brushes, and independently sealed waste collection bags.

2. Sewage Evacuation and Tank Wall Rinsing

   • Connect the suction pipe to the sewage outlet, start the vacuum pump to suck up liquid and solid residues from the sewage storage tank, and then inject clean water for a second suction to clean the tank walls.

3. High-Pressure Rinsing and Stubborn Stain Treatment

   • Use a high-pressure cleaner to spray the inner walls of the toilet, fixtures, and dead corners with a fan-shaped water jet, and repeatedly scrub calcified stains with a long-handled brush dipped in a cleaner.

4. Deep Disinfection and Rinsing

   • Spray or wipe disinfectant to cover all contact surfaces (such as door handles and flush buttons), maintain杀菌 (bactericidal effect, here meaning keep it for 10-15 minutes for sterilization), and then rinse off residues with clean water.

5. Air Treatment and Equipment Maintenance

   • Spray atomized deodorizers to neutralize odors, check components such as toilet seals and exhaust fans, and report any damage promptly.
   • Reserve clean water in the sewage storage tank and add biodegradable agents. Sewage and wastewater should be transported to designated facilities for standardized discharge.

6. Recording and Reporting

   • Fill in records such as cleaning time, disinfectant dosage, equipment status, and wastewater flow direction to ensure process traceability.

By combining daily maintenance with professional cleaning, the service life of mobile public toilets can be effectively extended, and hygiene and safety can be ensured.
