Once your candle has melted to less than an 1/2 inch and is completely harden, wrap the vessel in a dry paper towel. This will help aid in protecting the outside of your vessels from staining. With a butter knife, cut the remaining wax in 6 sections (pie like cutting). Use a spoon to scoop out each section, avoid touching the wax with your hands and then touching the vessels. Candle wax stains. To remove the wick/wick sticker, heat with a blow dryer and once heated you can spoon out the wick/wick sticker. Use alcohol to remove any sticky residue.
