(1) Preparation
Drain the engine oil: Drain the remaining engine oil in the can completely to ensure that there is no residual liquid.
Ventilation: Open all openings of the can body and ventilate it fully to ensure that the oil and gas concentration in the can is reduced to a safe range.
Wear protective equipment: Operators need to wear protective equipment such as gloves, goggles, and masks to avoid contact with harmful substances.
(2) Preliminary cleaning
Dry cleaning method: Use sawdust or dry cloth to wipe the inner wall of the can to remove residual engine oil and impurities.
Wet cleaning method: Use a high-pressure water gun to rinse the inner wall of the can to remove loose oil and impurities.
Chemical cleaning method: Use solvent-based or alkaline cleaning agents to dissolve oil stains, and then rinse with clean water.
(3) Deep cleaning
High-pressure water gun flushing: Use a high-pressure water gun to thoroughly flush the inside of the can to ensure that there is no residue.
Electric cleaning brush: Use an electric cleaning brush to deep clean the inside of the can, especially the bottom and corners of the can.
Manual scrubbing: For hard-to-clean areas, use a special brush for manual scrubbing.
(4) Drying
Natural drying: Place the cleaned engine oil tin can in a well-ventilated place and let it dry naturally.
Accelerated drying: Use a heat gun or hair dryer to accelerate drying, but be careful to avoid deformation caused by overheating.
(5) Check the seal
Check the lid: Make sure the lid is well sealed and not damaged. If the lid is damaged, it is recommended to replace it.
Test the seal: Pour a small amount of water into the can, seal it, and turn it upside down to check for leaks.
