R is for Review

I'm trying my best here to link a previous post title of mine that never saw publishing because I got something more attractive to post at the time. It was called: E is for Error Upon Erroneous Error. But now it's called something bland like Review.
In that previous title alone I don't know how many grammar laws I violated. I've probably slaughted the English language so many times it resembles something like the Butcher's shenanigans in the Five Point District.

What really irks me is when I read through my posts after publishing only to find grammar and spelling errors with each visit, and I would have spent a considerable amount of time "editing and reviewing" mind you. Sometimes if time allows I leave a draft for a couple of hours or a day and come back to it and re-edit. But once published. I can bet my last born, that I will find at least 3 incorrectly spelt words (or you where there's supposed to be your), etc. As you might guess, I am more than a little vexed by this seemingly chronic lack of attention to obvious details.

I read somewhere that when you edit, it's recommended that you read the text out loud and I found  that this does help to some extend. However, if I know what's coming, it seems as if I read from memory or something and therefore overlook the errors. So I need additional weapons to slay this illiteracy dragon.

How do I edit and review in a way that will almost guarantee fault free posts in the little time we have to do this?

HELP!!!
