3. Rinse: After washing, rinse or brush under running water. The lumen is flushed with a high pressure water jet or syringe.


4. Final rinse: After rinsing, rinse with soft water, purified water or distilled water. Rinse with a high pressure water jet or syringe in the lumen.


5. After cleaning, put the phone into the net basket and prepare to dry.


(2) Cleaning of automatic mobile phone washing machine


1. Check the working performance of the automatic cleaning machine and whether the enzyme cleaning agent, neutralizer and brightener are sufficient.


2. Insert the mobile phone heads one by one into the special jacks of the mobile phone cleaning machine one by one for full and effective cleaning.


Third, dry


Take the mobile phone one by one from the net basket or washing machine, use a high-pressure air gun or syringe to blow dry the surface of the pipe and the bearing of the wind wheel, or inject 75% ethanol to dry.


Fourth, disinfection


Disinfect the inside and outside of the phone with 75% ethanol.


Five, internal maintenance


Use a fully automatic oiling device to inject a special mobile phone cleaning lubricant into the inside of the mobile phone. If manual oiling is used, spray-type cleaning lubricant should be used.


6. Drying


After oiling, the appearance of the instrument should be dried in time, mechanical drying in the lumen, drying with a pressure air gun, and not drying naturally.

Twelve, matters needing attention


1. Do not immerse the phone in the disinfectant to avoid corrosion of the parts inside the phone.


2. Paper-plastic composite packaging paper should avoid being wetted by lubricating oil, so as not to affect the steam penetration during sterilization.
