Place an ice cube into a plastic sandwich bag. Hold the ice cube on top of the softened candle wax to harden it. Once the wax is hardened, scrape the wax off the upholstery with the back of a butter knife.
Apply a dry-cleaning solvent to a white cloth. Blot the area with the cloth for a few minutes.
Repeat Step 2 until all the candle wax is removed.
Set an iron on the lowest setting possible. Using too high of a setting could damage your upholstery. Allow the iron to preheat.
Place a white cotton towel over the top the candle wax. Rub the preheated iron over the towel for several passes.
Examine the progress of the candle wax by lifting the towel up. If there is still candle wax present, place a clean, white towel over the wax. Continue rubbing the iron over the area until you have removed all wax.
