To reduce the chance of a chimney fire
and to maintain efficiency, chimneys need periodic inspection
and cleaning. When selecting the correct chimney brush
for your chimney, first measure the inside of your chimney
and match that size to a brush below.
Keep in mind that:
An oversize brush will not improve
cleaning and could become lodged in the chimney.
An undersized brush will not provide the pressure on the
walls for proper cleaning.
How do I clean the chimney and control the Chimney Brush?
There are four common methods used in cleaning the chimney and controlling the brush.
Method one: Flexible chimney brush rod - top down.
Attach the brush securely to the flexible rod and lower
into the top of the chimney adding more rods as necessary
in order to reach the flue bottom.
Method Two: Insert
the brush and rod up through the fireplace damper or chimney
clean-out door. Add more rods as needed to reach the top
of the chimney. This method tends to create a mess since
sealing the bottom opening of the chimney cannot be done
during cleaning. Make sure to cover the area around the
opening to prevent staining carpets, furniture , etc.
Method Three: Line
and weight method: the best method to use when the top
of the chimney is permanently restricted by a covering.
Attach a compact 20 lb. weight (minimum) to one end of
the the chimney brush using a Chimney
Brush Pull Ring and attach a rope that is more than
longer enough to reach to the bottom of the flue, to the
other brush end. Seal off the chimney opening to prevent
soot from entering the home.
Method Four: Dual
line method: requires two people, one on the roof and
the other at the clean-out or chimney opening. Attach
a rope to to each end of the brush. Note -- you will need
to purchase two Chimney Brush
Pull Rings for each end of the brush. Drop one end
of the rope to the person below. Cleaning is done by alternately
pulling the ropes to move the brush up and down in the
For all methods, sweep or vacuum up all residue
prior to using the chimney. Be careful to check for debris
behind the damper, on the smoke shelf and in elbows and
T-connectors. Clean the chimney brush after each use and
coat with a rust preservative (WD-40 spray) works good.

How do I choose a Chimney Brush?
Use the following guide to select the proper
Chimney Brush for your chimney.
Measure the inner opening (both directions) of your fireplace or woodstove chimney.
For masonry chimneys you will need to measure
the inner opening dimensions in both directions. Purchase
a brush that is at least as big as your chimney liner
otherwise it will not reach the side walls of your chimney
and won't do an adequate job. If you buy a chimney brush
that is too big then it will be harder to get down the
chimney but will work unless excessively oversized.
Wire bristle chimney brushes such as the Rutland Chimney Sweep & Master Sweep are the most commonly used and do a good job. The Master Sweep series has more bristles and will generally make the job easier and faster. Wire bristle brushes are not recommended for metal chimney flues.
Poly chimney brushes are for use in metal chimneys and older fragile chimneys as they don't scratch the chimney walls. Standard poly brushes are very stiff and may be difficult to work into a very dirty chimney and also do not go around any bends that may be present in a chimney system.
