Leave them alone.

If you have like, 10 lemons or so done.

Let's predict you have 4 grammar errors and you'd need to add atleast two more detailed descriptions per lemon.

Now, let's predict you have posted them on more than atleast, two forums and one site. This means, you have to fix the same problems and do the same descriptions on every forum and site they are at. And if you would bumb a old topic just to spell tought Ken into thought Ken, people will grumble.

So in short, don't. No one is perfect. Especially, since if they are your older work, you can keep them as example as what you used to be and what you are now. Then you can avoid making the same mistakes again.
