I fully endorse the views expressed by fonegeeks and Mobilerepairlog. If you do it correctly, you are more likely to be successful than fail. I think, fonegeeks is very right when he says that "DO NOT use solvents or petrol on PCB's, as it will break the board down." I may be wrong but i don't advise excessive use of CTC for this purpose. Remember, CTC damages plastic and non-metalic parts. I strongly suggest the use of Liquid Detergents used for Cleaning Watch Parts etc.
