How do you get wax out of carpets?
Paper towels and a hot iron lay the towel down an place the iron on it
Do what mzzawesome say but use a water damp towel do it doesn't burn anything. Make sure it's a towel to throw away.
Ice the wax first. Pick off as much as you can. Then put paper towels over the wax area and iron ( watch its not too hot to melt carpet) and iron paper towel covered wax til it melts into the toweling. You might have to repeat it several times.
