Little common sense ：How to use the green oil for PCB ? 
We need to use the green oil when PCB oxidized , Place the green oil on PCB , Apply evenly with a toothpick or hard card , As far as possible thin .
Then let the PCB become dry under UV-light . also can let it dry under the strong sunlight .Your loyal friend - Pinkney , http://www.htic-tool.com
