    Hello,
    I open a topic with a question as above.
    A friend from the beginning of October was smoking twigs in the boiler room with freshly "modeled" pruners of fruit trees and thujas. Now he has a sticky and tarry soot in the stove and chimney.

    This slurry is a mixture of soot, tar and condensed water vapor formed in large quantities when burning wet material or when the temperature is set too low
    When it starts to burn with normal fuel, the water will evaporate and the rest will be cleaned mechanically with a brush
    I do not believe in chemical agents, I have not yet encountered a positive opinion about their effectiveness

    The problem is that this boiler has many nooks and crannies. On the other hand, mechanical cleaning with a not very handy wire brush by rubbing it on the slippery and sometimes very hard mud - is not only very difficult, but almost impossible.
    I saw a chemical agent in Castorama, I think it was called "SadPal" - and the seller praised it, the more that this agent is not very expensive.

    @Nicedog to begin with, you should burn it properly in this furnace. That would not soot settle.

    The chimney sweep, who regularly inspects our house, said that these sadpal agents clean the stove, the chimney is weak. Unfortunately, due to their chemical composition, they cause accelerated corrosion of boilers. Someone will say it's his money, so what should he say, but, firstly, he doesn't clean the boiler, secondly, I'm going to call him anyway, because I need the chimney sweep bill. Why don't you try Grandma's old recipe, potato peelings?

    I suggest the old grandparents way - Call the chimney sweep to clean the chimney... :)

    If the chimney is "freshly sealed" then you have to wait with the chimney sweep, burn dry materials in the stove properly, such as good quality coke (it varies with this), for a few weeks. After this time, when the tar oxidizes, call a chimney sweep and he will then brush everything away. It's best to do it from the roof, because at the end of the chimney, thick flanges are formed after such operation, which must be removed because they narrow the outlet cross-section.

    Let me tell you, my friend, you've made quite a mess. For me, after several years of burning wood in the chimney somewhere in the middle of the height, there was such a narrowing of creosote that even a chimney sweep ball could not crush it. It only helped to put a five-meter pipe into the chimney and hit it with a hammer from above.

    Well, my friend isn't that bad. Recently, he boasted that he used this agent for soot PalSad and burned the boiler a few times with dry wood and coke - and it helped very effectively.

    Since the problem has already been solved - it remains to close this topic and thank all participants of this forum for taking part in the discussion. :)

Topic summary

The discussion centers on effective methods for removing tarry, sticky soot from a boiler and chimney, particularly after burning wet materials like twigs. Participants highlight that this soot is a byproduct of burning wet wood or low-temperature combustion. Mechanical cleaning with brushes is challenging due to the soot's consistency, and while some suggest using chemical agents like "SadPal," concerns about their effectiveness and potential for causing boiler corrosion are raised. The consensus leans towards burning dry wood or coal to facilitate natural soot removal and recommends hiring a professional chimney sweep for thorough cleaning, especially for chimney blockages. Traditional methods, such as using potato peelings, are also mentioned as alternatives. The original poster later confirms that using the SadPal agent combined with dry wood burning proved effective in resolving the issue.
