Take AHLR03-DF3, stir and soak in the medicine heated to 90~100°C for 30 minutes, take it out, and rinse it with clean water. This formula was found to be the cleanest. The picture on the left is before cleaning, and the picture on the right is after cleaning.

Results and discussion:
Because the gap between the enameled wire and the wire is very small. Generally speaking, as long as the gap is less than 100 μm, the drug is not easy to flow in the smaller gap due to the effect of its own viscous layer. It is recommended to heat the agent and spray it with high pressure; or add ultrasonic waves to assist the agent to flow in the gap, which can improve the cleaning efficiency.
