What are the benefits from using the Creososte Sweeping Log ?

1 - How the CSL Works ?

a 4 steps treatment
1. The Creosote Sweeping Log burns for approximately 90 minutes. Making a wood fire prior to using CSL will heat the tar on your chimney wall, while it improves your draft.
2. The smoke from CSL is charged with additives, which rises and attach themselves to the creosote deposits.
3. Next, these creosote deposits are either reduced and/or rendered less likely to result in a chimney fire, making your next fire safer.
4. While burning fires over the next 1 to 2 weeks, the CSL additives which are attached to the creosote will continue to treat your chimney. Some creosote may fall back into your fireplace, smoke shelf or woodstove.

All flue pipes. Masonry flues. Catalytic converters.


BBQs, gas logs, electrical appliances, oil stoves, pellet stoves.

3 - How many CSL do I need ?

Using the CSL with Woodstove or Fireplace insert.

Woodstoves are well known to produce high amounts of creosote inside the flue pipes. Burning only one CSL in a wood stove or fireplace insert will reduce overall creosote weight, thickness & volatile organic compounds. Therefore, to keep your woodstove or fireplace insert in good condition, follow the guidelines in the chart below according to your woodstove or fireplace insert usage.

CSL Usage frequency

Creosote build-up will depend on appliance type, fuel used, frequency of use and other factors.

For Woodstoves, inserts and small fireplaces, use 1 CSL at a time:
  • For best results, place the CSL on the hot embers after you have burned a regular fire.
  • Never place the CSL on an active fire.

Regular chimney inspections are always recommended. The CSL will not tell you if your chimney is blocked or has any kind of structural damage. The CSL does not take the place of inspection and professional cleaning.

4 - The benefit of using CSL

CSL's active ingredients effectively reduce creosote build-up in your chimney or flue. Our new and improved triple action formula also helps prevent new creosote build-up in flue pipes.

A clean flue uses less wood to efficiently heat your home, which is great for the environment and saves you money.

Keeping your flue clean will create a proper draft, allowing toxins from wood combustion to safely exaust outside.

CSL is environmentaly friendly

Without treatment or removal, creosote can build-up to the point where:

  • The flue is severely restricted, limiting the air flow and causing the woodstove to operate poorly.
  • The heat transfer into the room is reduced due to insulation effect of the creosote coating.
  • The draft will decrease, allowing dangerous toxins to enter your home.
  • The creosote build-up can combust causing a chimney fire.
