Remove reset entries from git reflog (cleanup)

Question

Is is possible to cleanup repo state so that reset history is removed from reflog?

I did a bunch of reset-hard to find a bug, but then I want to go back to main master state... I mean, I'm kind of at the master state, but reflog remains. Can I cleanup those? Or would I have to re-clone the origin?
