   W: This is Lucy Withers, and you're listening to the Home & Health show on Radio 88.9. Today's helpful hint has to do with candles. I love burning candles in the house. They scent the air and their flame creates a warm glow. So often, though, the hot wax will drip from the candle onto our nice furniture, or even worse, a tablecloth. How to clean the wax from cloth? The solution is simple, but it will require a bit of manual labor. Get out your iron and find a brown paper bag. Put the paper over the spot of wax and iron it so that the wax melts. The melted wax will stick to the paper. Continue doing this until all of the wax is gone. Replace the paper when it becomes thoroughly soaked with wax. When you're finished, there's one last step. Wash the cloth either in a washing machine or by hand. That's it!
