Question: Hello, I am very interested in fireplaces! I would like to know is it really hard to clean them. Because my dad said that he going to make me clean our fireplace if i didn't stop setting fires.

You then either use rods to push the brush down the chimney...or use a rope (from the top) with a weight on the bottom of the brush...Or, you can hire a professional chimney sweep for about $100.00 to sweep the chimney.
