I have never had an issue with real Dean's Ultra or generic T-type plugs when using a bit of flux like squee said. Just make sure to use the flux sparingly, it has such a low viscosity when heated it can actually flow to the other side of the plug and gum everything up. This happened to me last time I soldered on a few Dean's, had to use rubbing alcohol and Goo Gone to get rid of it.
