Removing labels is super easy.
Oxyclean and hot water in a Home Depot "homer bucket" or similar; soak the bottles for a couple hours. (I usually go overnight.)
When you come back all the normal* labels will be off, and just floating around. You may need a little light rub with a sponge or washcloth to get the las off the glue off, but it's really that simple.
*Some brands use insane glue or wired plastic labels, or even painted labels. Just don't bother with these. If you soak overnight, and the label is barely loose, just recycle it.
