This is probably a silly question. I am adding an outlet to a circuit in my garage. I'm putting up 1/2" plastic conduit and it will have some 45 degree bends in it to get around a drain pipe. I'm using one #12/2 NM for the new run. Is it o.k. to use just a drop of liquid soap, like Dial or something, to help get that wire through the pipe? I wasn't sure if it would harm anything or go against any code.

Thanks!
