Freeze-Off is supposed to be a penetrating fluid, but doesn't work well in that respect. However, it is very useful for getting parts to shrink a bit so they're easier to take off. Basically, you're doing this unevenly so the cog and hub are slightly different sizes as you would when applying heat.
