How do I delete all my tweets?


I now have two accounts and one has more than 90 thousand tweets. I want to use the one with 90k+ tweets for my blog, and use the other for my personal twitter. I would usually just delete the twitter but I don’t want to lose the verified accounts that follow it, yet I want the twitter to be ‘new’, I don’t care if the icon is still there saying 90k+, I just want the back catalogue gone. Is there any way to delete all of my tweets on the 90k+ account? Thanks.
