1. Pre-drying: After cleaning, invert the can to drain all remaining liquid. Thoroughly wipe the inside and corners of the can with a dry cloth to prevent water accumulation.
2. Temperature and Humidity Control: Place the can with the opening facing upwards in a well-ventilated area with a temperature of 20-25℃ and humidity below 60%. Use a fan to blow air directly into the can to accelerate moisture evaporation.
3. Auxiliary Dehumidification: You can stuff dry paper towels into the can to absorb moisture, or add a small amount of desiccant. Alternatively, you can gently blow warm air (not exceeding 60℃) into the can to quickly remove residual moisture.
4. Final Verification: After standing for 2 hours, wipe the inside with a dry white cloth and seal the can with paper towels for testing. If no signs of moisture are found, the can is considered completely dry.
