acetone polish remover will be the fastest way to get rid of them. It's the easiest too. If you have been wearing them for a while, or the person filed too much when they were put on (common), they will be VERY tender and sore; just a bit tender and sore if done right. I'd put a clear, nail hardener on them to protect them until it all grows out. Also, keep them short until they are completely grown out.
