How to use our chimney & flue cleaner

  1. Make a good hot fire and allow it to die down to hot coals.
  2. Adjust unit, if possible, so airflow is travelling up the flue slowly.
  3. Place sealed sachet of Soot-Loose on the hot coals (no need to cut sachet open, as packet will burn during process). If using a tin: Place 2 heaped tablespoons on the hot coals.
  4. After 15-20 minutes, the process is complete.
  5. Re-ignite the fire to allow any loose soot remaining in the flue to be flushed out.
  6. CAUTION – In the case of an open fireplace: Place a guard in front of the fireplace to protect any persons, floor coverings or furniture, as hot soot may fall from the chimney/flue back into and around the hearth.
  7. If the chimney/flue is heavily sooted, use 2 sachets of Soot-Loose in a single application.
  8. When using your heating unit regularly, Soot-Loose should be used once per week.

A yearly inspection of your chimney/flue by a professional is recommended.

Your Rating

Can pregnant woman use it?

Yes, anything that can cause fetal abnormalities has to be stated, by law, globally.

How does it work?

The Soot-Loose contains a solvent that only reacts on heat. When the product is placed onto the hot coals, the solvent is released. The solvent then follows the air flow up the flue. When it comes in contact with soot deposits, it works by dissolving the tar that holds the soot together.

How and when is the best time to use Soot-Loose? (how high must the flame be)

The optimal time to use Soot-Loose is at the end of the burn, when the air flow is traveling up the flue slowly. Soot-Loose will not be effective if the air flow is traveling fast, as it will not have time to react. (No flame/when flame has died down)

Is your Soot-Loose product suitable for flues where the roof is used for water catchment (domestic water tanks & drinking).

The Soot-Loose should not be an issue for drinking water. The product is designed to soften up the resins and tars that line the inside of the chimney flue – causes them to collapse and drip back down into the fireplace to be properly consumed by ongoing fires. It does not cause residues to come out and land on the roof, certainly no more than you would get without using Soot-Loose.

I’ve placed the sachet of Soot-Loose on the hot coals and let it go over night, and when I checked this morning there was still black product left in the sachet, is that right and has the product worked?

Yes, at 250 degrees the heat will pop the sachet and the active ingredient will evaporate up the flue. The carrier ingredients will usually remain in the sachet.

Do I close the door when I use Soot-Loose sachet or leave it open?

You need to close the door for best results.
