Fill a bowl with warm, soapy water and soak your nails for 5-10 minutes.
Gently remove by using the provided cuticle pusher to gently lift the edges of the fake nails.
Repeat: If they don't come off easily, soak for a few more minutes or add acetone into the solutions, but keep in mind, acetone will damage the fake nails, which are otherwise re-usable.
