Your coming back to it later tactic is a good one. A lot of times, you get caught up in your own work and miss the simple things. You know the idea you want to express, so you gloss over the sentences, knowing what to expect. If you step away for a while, you get some fresh eyes on it. Also, using a word processing program will help a lot with the homophones (their, there, they're). Pay attention to the squiggly underlines. Another idea is to let someone else read it. Then you get a completely new set of eyes to look at it. They'll find out more than you ever could on your own.
I agree with this. Anything important should either have an actual editor look over it, or you should leave it for at least 2 weeks before reviewing it yourself. Longer is better. The problem is that we tend to know what we think we've said, rather than reading it as if we were a reader with no preconceptions.
