Eliminate foul chimney odors with regular cleaning.

A foul odor coming from your chimney is commonly caused by a mold accumulation, which permeates through your home whenever the fireplace is in use. The smell is both unpleasant and harmful to your health, as mold diminishes your ability to breathe when regularly inhaled. Although a professional chimney cleaner can eliminate musty smelling chimneys, you can also clear out the chimney yourself with a chimney cleaning kit. Once initially cleaned, the chimney requires monthly cleaning to maintain a clear flue to prevent mold from returning.


Step 1

Lay a sheet of plastic over the front of the fireplace to protect the area from mold and debris. Cover all of the room's furniture with plastic sheets to prevent mold from attaching to the upholstery.

Step 2

Place a surgical face mask to prevent breathing in mold, put on gloves to protect your hands and cover your eyes with plastic goggles.


Step 3

Attach the chimney brush to the end of the chimney rod, and insert the rod into the fireplace. Brush the chimney brush against the inside of your fireplace to remove buildup on the flue.

Step 4

Turn on the flashlight and check the fireplace once the debris has settled to ensure it is clean.


Step 5

Pick up the plastic sheet carefully to prevent spilling the debris on the floor or carpeting, and sweep up any debris from the floor with the broom.

Step 6

Remove the plastic sheets from the furniture and dispose of the plastic in a garbage bag outside of your home.
