Answer 1: Removing Candle Wax from a Tablecloth -- Heloise Hints - Good Housekeeping
For a tablecloth or other material, put it in the freezer for several days, to freeze and dry out the wax. Flick off big chunks and then put paper towels over and under the stain and press with the iron. Rub straight liquid laundry detergent into the area, let set for a few minutes, then wash in the hottest water safe for the fabric.Speaking of candles, storing them in the freezer is not recommended because it will dry them out. However, keeping them in the refrigerator is okay, but be sure to put them in a plastic bag or wrap in plastic so the wicks don't absorb moisture.


Answer 2: How to Get Wax Off a Tablecloth - eHow.com 

1. Scoop up excess wax with a spatula or a spoon.
   
2. Lay the tablecloth on an ironing board, and place a plain paper sack over the wax stain. Apply a warm (not hot) iron to the paper. Replace the wax-saturated paper bag as needed. Continue until wax is no longer transferring to the paper.
   
3. Treat colored candle stains with a prewash stain remover, or apply detergent directly on the spot prior to washing. (Remember to pretest spot removers and stain removers in an inconspicuous area prior to treating stains.)
   
4. Launder the tablecloth with detergent in the hottest water that's safe for the fabric. Wax-based stains must be melted to be removed from the fabric fibers.
   
5. Make sure the stain is completely removed before placing your tablecloth in the dryer. If you're unsure, wash, wash again
