Hi
 I've used peanut oil and a fry pan. Then wash the
parts in detergent to remove the oil. You need to wear
gloves and goggles as safety gear. Hot peanut oil
in your eye is not something I'd like to even think about.
 Make sure that the assembler didn't bend the corner leads
of the ICs. If they did, you'll need to straighten them
before the oil, using a soldering iron.
 It just seems to me that the oil method is a little more
controlled than a torch.
