  1. Make a 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 (packet will burn during process).
  4. After approx. 15-20 minutes, the process is complete.
  5. Remove any loose soot from above the baffle plate before restarting the fire.
  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.
  7. If the chimney/flue is heavily sooted, use 2 sachets in a single application.
  8. While heating unit is in constant use, apply Soot-Loose monthly. Your chimney should be nice and clean.


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.

Soot-Loose Chimney & Flue Cleaner

Get The Soot Out!

This is my first house with a fire and it is 12 years old. I don't think the flue had been cleaned before because so much soot has come away after using the Soot-Loose granules! I will definitely be buying this product again.


I am a semi-retired 72-year-old technology studies teacher, i did not want to climb on my roof to sweep out the chimney flue. 100% sceptical, I decided to give Soot-Loose a try because it was so inexpensive to buy so that if it did not work, it would be no big deal. As per instructions, two days ago, i tossed a sachet onto the embers of the fire as it burned down and then just let Soot-Loose do its job. Yesterday, when I removed the baffle plate to see if it had cleared out any gunk from the flue pipe, I discovered over 2 killograms of soot and other 'stuff' sitting like a mini-mountain on top of the baffle plate. IT WORKS was my shocked, but very pleased response to this discovery. Even better, the fire drew air in smoothly with no smoke alarm going off whenever i opened the door to put more wood in. The fire also used significantly less firewood, with only a small amount of fine ash left in the firebox. My wife is also very pleased, not only does our slow combustion heater work like it did when it was new, i no longer need to climb on the roof, which is a great relief to her. To other reasonable-minded skeptics, I have this simple message, Soot-Loose works.

So glad I gave it go

Having tried similar products I was at first a little sceptical about this Rubbedin product. Anyway, I began using it on a weekly basis from the start of last winter. I'm happy to report that it worked brilliantly. No problems whatsoever, no more climbing up on the roof to sweep the chimney was a big bonus! You can rest assured I'll be back for more.

Safe and easy

I am so grateful that there is such and easy and effective way to clean out chimneys and flues. Cleaning the flues is essential to avoid house fire, as the build-up of soot etc can actually catch alight, sending up embers and causing the fire to the house and the surrounding bush. This product saves my husband having to climb up on the roof with a chimney sweep (oh, the hazards that can cause). We have an oven and a fireplace which means double the danger and double the need for this terrific product. I use it at the start of winter each year, so know that I and mine will be safe for the season. You can actually hear the soot breaking off and falling back into the fire, so you know it's working, it all burns up safely, then you simply toss out the ashes as normal. Easiest job in the house now and I can do it myself - no ladders, no brooms, no ash and soot through-out the house! Thanks, Rubbedin.
