How to clean and reuse Metal Can For Oil

To clean and reuse Metal Can For Oil, you need to follow standard procedures to ensure safety and durability. First, completely dump the remaining oil in the barrel in a well-ventilated place away from fire sources, and wipe the inner wall with oil-absorbing paper or cotton yarn to avoid residue.
Then enter the cleaning stage. First, use a high-pressure water gun to rinse the inside and outside of the barrel to remove surface sludge and impurities; for stubborn oil stains, you can prepare an alkaline cleaner (such as sodium carbonate solution) or a special degreasing agent to soak. After the grease softens, use a long-handled brush or barrel washer to deeply scrub the inner wall, bottom and barrel cover gap. If acidic and alkaline oils were previously stored, the corresponding neutralizer needs to be used for neutralization reaction, and then rinsed repeatedly with clean water. After cleaning, turn the oil barrel upside down to drain naturally, or use a hot air blower or compressed air to dry the inner wall to prevent moisture residue from causing rust.
When reusing, first check whether the barrel body has rust, dents or cracks in the weld, test the sealing, and replace the sealing ring in time if it is aging. Follow the principle of "special barrel for special purpose" to avoid cross contamination of different types of oils, especially industrial oil and edible oil cannot be mixed. Before use, mark the name, specification and replacement date of the stored oil on the surface of the oil barrel for easy management. Regular maintenance and inspection, timely handling of problems found, to ensure the continuous and safe use of the oil barrel.
