Shelf life of warm wax

[Jophiel]

Hi, does warm wax have a shelf life??

I'm not sure what the shelf life is if the tub is unopened, however there is definitely a limit on how many times you can heat it up before it starts to become brittle and loose its stickiness. This would vary between brands I think.
I keep the 'dregs' of wax and use them up on myself!
