I paused my fb instead of deleting the account because I didn't want to lose all my contacts on messenger. Now I need to go back to using fb for my online biz... really no choice. So I need all my history deleted so my online presence is politely neutral and doesn't impact the business. I found this article... is this the best way? Thank you for any help.

This is the answer. Make a brand new fresh account for business and delete the okd account
I thought you couldn't delete everything by using Facebook settings because they make you go through every single item manually
