Should you sterilize perlite between uses in a shotgun FC?

I fruited in a shotgun a while ago and it's been sitting there since. Do I need to sterilize the perlite before I use it again? If so how would I go about that? I read you can bake it in the oven but there's so much perlite no way in hell I'm doing all that. Is there a more convenient method?

Turkey roaster, canning stock pot are some cooking containers that would hold a lot more. Buy new, its not that expensive. Rinsing with hot water might be sufficient.
