Thinking that you can totally erase such records is wishful, but not anywhere in the realm of realistic. No matter what criminal background or public or private databases you manage to find, pressure, or even get court orders against, unless you have the ability to un-archive web pages around the world, un-publish newspapers, un-broadcast news reports, un-fill-in jail booking lists (which remain public record) or have a time machine, you will NEVER eradicate all records - most of which will REMAIN easily and readily available (and usually for free) to those who know where and how to look. You may succeed in getting the major services who provide such database checks to employers for a fee to remove the record, and that would get you past most such checks, but if an employer actually wanted to get hands on, or uses a service who goes BEYOND just a standard database check, MANY types of records, both public and private, are made in conjunction with any arrest that doesn't and won't cease to exist, even with an expungement. That's not meant to discourage you, only to point out that such successes are very "surface level", and "deeper" employers or anyone curious enough to do a little research find expungement to be an annoying bump at best.
