1. Drain any remaining oil
Turning the oil tank upside down ensures that all remaining oil drains out completely to avoid waste.
Use an explosion-proof pump and a large forced-action filter to remove any remaining oil, ensuring safe operation.
2. Initial Cleaning
Use a brush or sponge with dishwashing liquid or soapy water to thoroughly scrub the interior and edges of the tank.
Stubborn oil stains can be softened by soaking in hot water before cleaning. Avoid scratching or damaging the tank with hard objects.
3. Deep Cleaning
High-Pressure Cleaning: Use an explosion-proof pneumatic high-pressure washer (1000 rpm) to clean the tank 360 degrees, ensuring no blind spots are left.
Second Cleaning: Repeat the high-pressure cleaning process to increase the cleaning efficiency to over 99.5%.
4. Deodorization and Disinfection
Pour white vinegar and hot water into the tank and let it sit for 30 minutes to break down any remaining odors, then rinse thoroughly. Disinfect with diluted bleach (1:10), then rinse several times with clean water to remove any chemical residue.
5. Drying and Acceptance
Air dry the container or use a hair dryer to accelerate drying, ensuring no moisture is left inside.
Acceptance Criteria: No oil stains or odor on the interior surface, and no stains when wiped with a white cloth.
6. Safety Precautions
Use explosion-proof equipment throughout the entire process, ensuring grounding and equipotential bonding to avoid static sparks.
Industrial-grade cleaning requires professional personnel. When performing personal cleaning, ensure proper use of protective gloves and proper ventilation.
