Any other methods for loosening figures joints?

[nightwing]

I have read before that you can boil a figure to loosen up a joint but are there any other ways?. I recieved a petey williams and another rhino both have stiff joints. I have gone through 3 rhinos with stuck arms that will not move. The other 2 rhinos broke when I slowly tried to move their arms down. I have 12 other TNA figures with no joints problems and these are the only two figures I've had like this. Any help would be appreciated.

I put any loose jointed figures of mine on the fireplace when I have it on. They get soft enough to maneuver them around enough. If you don't have a fireplace, use a hairdryer maybe...

The water doesn’t need to be at a boil. I was and still am a little weary of putting an action figure into boiling water so I tried with hot tap water and it worked ok. I've never tried a blow dryer but I hear it works ok too.

Boiling water is a good method. If your worried about something happening..just watch the fig.

I only worry about putting the figures head or bodyparts with logos into boiling water because i fear the paint on logos or face detail will melt away....
