Safety & First Aid

SAFETY DIRECTIONS: Keep out of the reach of children. Avoid contact with skin and eyes.

FIRST AID: For advice, contact a Poisons Information Centre (e.g. phone Australia 13 11 26; New Zealand 0800 764 766) or a doctor.


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

Is the Soot-Loose dangerous to people or the environment?
No, Soot-Loose does not contain harmful or corrosive chemicals.

Will Soot-Loose corrode my metal flue?
No, Soot-Loose is the only chimney cleaner available that is based on an organic solvent and does not contain corrosive salts.

How often should I use Soot-Loose?
We recommend that you use Soot-Loose weekly during periods of use

How do I know if I need to clean the flue?
Generally a dirty flue will generate a lot of smoke. Also, you may hear crackling in the flue when the unit is in use.

What type of heating units and flue is Soot-Loose suitable for?
Soot-Loose is available for all types of heating units, including open fireplaces and brick flues.

I am about to try this product in my wood heater and was wondering how it works. I understand it is magnesium, can you explain how it does this?
Soot loose works by releasing the chemical agent as the char is being burnt up. The chemical slowly moves up the chimney or flue and breaks down the soot and creosote

What do I do if I haven’t cleaned my chimney in over 10 years/ ever?
Use an entire 250g tin or 5x sachets all together and follow as per instructions.

I have a double burn wood heater, is it ok to use Soot-Loose?
Yes it is ok to use Soot-Loose on a double burn wood heater

Can I use Soot-loose on a Webber Kettle?
Not recommended as never been tested with this product. If build up caused by oil and food residue suggest BBQ Magic.

My dog has eaten some Soot-Loose, what will happen?
Soot-Loose is Non-toxic, however the active ingredient can be dangerous if large quantities are consumed. A Soot-Loose sachet contains 8g’s of active ingredient and the fatal dose is 3.6g per kg of body weight. Symptoms of ingestion are headaches, dizziness, nausea and vomiting. If this occurs take to the vet straight away. Make sure your dog drinks plenty of water.

What is “SOOT”?
The fine black particles, chiefly composed of carbon, produced by incomplete combustion of coal, oil, wood, or other fuels.

What is ‘TAR”?
A thick, black, viscous liquid obtained by the distillation of wood, coal, etc., and having a varied composition according to the temperature and material employed in obtaining it.

What is “Creosote”?
A colourless to yellowish oily liquid containing phenols and creosols, obtained by the destructive distillation of wood tar, especially from the wood of a beech, and formerly used as an expectorant in treating chronic bronchitis.

Can I use Soot-Loose on my wood burning stove that has a catalytic converter?
Yes you can use Soot-Loose on a wood burning that has a catalytic converter

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.

Can I use Soot-Loose in a gas fireplace?
Yes you can. But as gas heating is cleaner than normal log burning methods it is not necessary unless you feel as though it needs to be cleaned. We understand gas heating does cool down a lot quicker, so we recommend turning the heating onto the lowest setting.

Can I use this in a combustion oven?
Yes as they are similar to a normal fire place. The formula is also non-toxic with organic based ingredients so it is safe near food areas.

Will anything flying out the chimney affect my solar panels?

The creosote soot, and tar will fall down the chimney – anything light enough will go up with the smoke and fly away. If anything does land on the panels, it’ll be no different than the dust in your home.
