>>6247593It's not about being "hard".
I don't generally buy one figure at a time, and I have multiple joints to address, almost every time.
So I treat them all. The bath hits every joint. I don't have to worry about pegs snapping like my first run in with Spider-Gwen, whose foot snapped off almost immediately after opening.
I bought the Juggernaut line, except Deadpool. Every figure had at least one stiff joint, include Iceman with a stiff shoulder and elbow, despite every other joint being the typical floppy you get with translucent figs.
The whole Strange/Dormammu and Red Onslaught lines had similar issues. My 2nd attempt at Spider-Gwen, and Yellow Suit DD. Even the new Old Man Logan and Colossus.
Generally they have either a one stiff knee, one foot, or one half of one of the double-joints on the elbows are stiff. Mid-limb articulation,is especially prone to the stiffness on the older figures, probably from sitting on the shelf so long.
>>6247534Another bonus about the heat bath is that, since it softens the entire figure, you can fix package-induced bending. My Wolverine's head and calf points were too bent, and his claws crooked. Warm bath loosened the joints, then I fixed the bending issues and placed him in cool water. Boom, fix'd.
