Best advice I have for making boiled eggs as easy as possible to peel is as follows:
1. Make sure you don't use eggs that are super-fresh (a week in the fridge is best, maybe even two if you get them straight from the farm)
2. Don't put the eggs in cold water and then boil. Slowly lower them into a pot of already boiling water using a spider or large spoon.
3. Cook to desired yolk done-ness (there are many recommended timings for this, you'll have to play around with it)
4. Immediately plunge into an ice bath, and then peel
For acid, I would try a splash of rice vinegar in each bowl, or maybe even a traditional black vinegar if you can find it.
