1. Ensure satisfaction with the requirements for cleanliness of parts. In repair, the level of cleanliness required varies among different components. In the device, the cleaning requirements for cooperative parts are higher than those for non cooperative parts, dynamic cooperative parts are higher than static cooperative parts, and precision cooperative parts are higher than non precision cooperative parts. The cleaning requirements for the surface of sprayed, plated, and bonded workpieces are very high. When cleaning, it is necessary to adopt different cleaning agents and methods according to different requirements to ensure the required cleaning quality.

2. Prevent corrosion of parts and do not allow any degree of corrosion on precision parts. When the parts need to be parked for a period of time after cleaning, the rust prevention ability of the cleaning solution or other rust prevention methods should be considered.

3. Ensure operational security to prevent fires, poisoning of human health, and environmental pollution.
