1. Initial Cleaning
Clean Water Rinse: First, rinse the inside and outside of the can with clean water to remove any remaining oil residue and any large clumps of oil.
Detergent Cleaning: Mix clean water and detergent in appropriate proportions and thoroughly clean the inside of the can to break down any oil residue.
Secondary Rinse: Rinse thoroughly with clean water to avoid any detergent residue.
2. Deep Cleaning Methods
Baking Soda and Sand Method: Add baking soda and sand to the can, add hot water, and shake. This will use friction and chemical reactions to remove stubborn oil stains.
Dishwashing Soap and Rice Method: Add dishwashing soap, rice, and warm water, shake, and use the friction of the rice to clean the inside.
Eggshell Method: Crush eggshells, mix with hot water, and shake. The calcium in the mixture will break down any oil stains. 3. Environmental and Safety Precautions
Protective Equipment: Wear gloves, a mask, and goggles during operation to avoid contact with skin.
Ventilation Requirements: Ensure ventilation in the cleaning area to prevent the accumulation of harmful gases.
Wastewater Treatment: Cleaning wastewater must be filtered or settled before discharge to avoid environmental pollution.
4. Other Practical Tips
Toilet Paper Ball Method: Roll up toilet paper, dip it in detergent, place it in a can, and shake it to absorb the oil, then rinse.
Rice Water/Tea Water: Use the alkaline properties of rice water or tea water to remove oil, which is environmentally friendly and effective.
