Cleaning Steps for Mobile Toilets

The cleaning steps for mobile toilets can be divided into two types: professional cleaning procedures and the eight-step cleaning method, as detailed below:

Professional Cleaning Procedures

1. Pre-treatment: Operators must wear full protective gear (waterproof aprons, non-slip rubber boots, nitrile gloves, goggles) and set up mobile warning signs to isolate the work area. Focus on inspecting the liquid level indicator, sewage valve connection status, and ground leakage to ensure safe operation.
2. Emptying Waste: Use a high-power vacuum truck connected to the sewage outlet to slowly extract liquid and solid residues from the storage tank. After completion, inject clean water for a second extraction to thoroughly flush away any residue on the tank walls and prevent waste buildup.
3. High-Pressure Washing: Utilize a high-pressure washer with a pressure of 120-180 bar to spray the toilet interior walls, fixtures, floor, and corners with a fan-shaped water jet, focusing on removing fecal matter, tissue residue, and calcified dirt. Stubborn stains require scrubbing with a long-handled brush dipped in non-ionic surfactant cleaner.
4. Deep Disinfection: Apply chlorine-based or hydrogen peroxide disinfectants (effective chlorine 500-1000 mg/L) by spraying or wiping to cover all contact surfaces (such as door handles, flush buttons, handrails), maintaining contact for 10-15 minutes before rinsing with clean water. Simultaneously, disinfect the sewage suction hoses, connectors, and tools to the same intensity to prevent cross-contamination.
5. Air Treatment: Use atomized deodorizers to neutralize ammonia and hydrogen sulfide odors, improving the toilet's air quality.
6. Equipment Maintenance: Inspect components such as toilet seals, exhaust fans, door lock hinges, and solar power systems, recording and reporting any damage promptly to ensure normal equipment operation.
7. Waste Disposal: Transport the extracted waste and cleaning wastewater to designated sewage treatment facilities or septic tanks for proper disposal. Dumping into storm drains or non-designed sewer networks is strictly prohibited to avoid environmental pollution.
8. Record Keeping: Fill out a record form including cleaning time, disinfectant usage, equipment status, and wastewater flow direction for easy follow-up and management.

Eight-Step Cleaning Method

1. Dust Removal: Use a broom to remove dust and cobwebs from the ceiling, walls, window screens, and lighting fixtures, maintaining a clean toilet environment.
2. Wiping: Use a cloth to wipe down frequently touched areas such as doors, windows, handwashing stations, partition boards, window sills, walls, and switches to remove surface stains.
3. Scrubbing: Use a brush to thoroughly scrub alkaline scale from squat toilets, sit toilets, and urinals to prevent blockages and odors.
4. Sweeping: Sweep internal and external toilet garbage, promptly emptying trash bins to prevent bacterial growth from accumulated waste.
5. Mopping: Use a mop to remove standing water from the floor, ensuring internal dryness and cleanliness to prevent slipping accidents.
6. Inspection: Check faucets, sensor devices, clothing hooks, and other facilities for damage, reporting repairs promptly to ensure functionality.
7. Disinfection: Spray disinfectant solution on high-frequency contact areas such as door handles, faucets, and switches (at least three times daily) and activate deodorizing equipment or light deodorizing incense to inhibit bacterial transmission.
8. Storage: Store cleaning supplies (mops, brooms, cloths) in the tool room, ensuring the toilet is free of clutter and maintaining overall order.
