How to I delete an unrequired user profile property from web.config and the database?

Question

I use the default ASP.NET Profile Provider which lets me define user properties in web.config.

I now no longer want to use one of these user properties. I want to delete all traces of it.

I can remove the property from the list of properties in web.config however, I suspect, the stored values for this property will still be held in the aspnet_Profile table for each user.

Is there an easy way to clean out all traces of the data for a property that's no longer used from the aspnet_Profile table?
