I do one hand at a time usually, it only takes a few minutes per hand.
1) cut cotton balls in half using scissors (I use full sized cotton balls on the thumbs)
2)get a cotton ball mostly saturated in 100% acetone polish and place over each nail
3) secure in place by putting a childrens cloth ponytail holder over the nail to keep the cotton ball in place. I have also used twist ties, but I find these lil stretchy bands work best. I bought like 100 of them in the childrens section of a dollar store. I reuse them too.
4) make a "thumbs up" sign, like you are hitchhiking
5) while making the thumbs up sign, press the nails into the palm of the hand applying pressure to the nail beds, alternate applying some pressure to the thumb too.
6) Polish wipes off EASILY in about 3 minutes.
Here's what it looks like
