Okay... here's another chapter on cleaning
1. using the rectangular selection, take apart a big chunk of the image and clean it
2. after cleaning it, see how it changes.... see how much work would you have saved if we would have used a more complicated image?
3. there's still a tough place... look at that annoying reborder.... if we left it that way, the final product would look quite ugly, and we don't want that.... but using the lasso, or the magic wand is too hard in here
4, 5, 6. Use the magic wand, select the clean part (not the reborder), right click and Selection>grow.....
7, 8 just add the properties (this is a very delicate process, so be carefull to not to take a big part of the image

... once done, you'll instantly see how much did the selection grew
9. after cleaning it, you see a perfect border.... easy huh?.... you may notice that some small part of the image was lost, but don't worry, it isn't too significant
I hope that clears it enough
