Ways and tips on how to clean the chimney in the bath


Out­side the city, a favorite place for many peo­ple is a bath­house. Dur­ing the com­bus­tion of some mate­ri­als, soot and soot accu­mu­late on the walls. If you heat the bath with wood or coal, then the pre­cip­i­tate forms on the inside of the pipe quick­ly enough. Against this back­ground, the lumen of the pipe decreas­es, which can cause a fire. There are sev­er­al ways to clean the chim­ney and remove the block­age in the fur­nace chan­nel in the bath.

Types of blockages in the chimney pipe

When wood burns, car­bon monox­ide and smoke are released. The black tint is the result of soot, coal and cre­osote.

Pipes in the bath can become clogged for sev­er­al rea­sons:

  • the for­ma­tion of soot and soot;
  • accu­mu­la­tion of con­den­sate;
  • ingress of for­eign objects;
  • resin depo­si­tion;
  • accu­mu­la­tion of ash.

All wood con­tains resin. When heat­ed, they decom­pose and volatilize. In the future, they set­tle on the walls of the pipe. With fre­quent use of the bath, deposits are lay­ered on top of each oth­er and there is a high prob­a­bil­i­ty of com­plete block­ing of the through hole. The thick­ness of the lay­er depends on the struc­ture of the sur­face.

The for­ma­tion of block­ages can be affect­ed by a vio­la­tion of the rules for lay­ing the chim­ney, as well as poor-qual­i­ty mate­r­i­al from which the chan­nel is made.

The chim­ney can become clogged when burn­ing garbage: plas­tic bot­tles, ply­wood, fire­wood with paint, etc. As a result, the oxide from the garbage will set­tle faster.

The rate of heat­ing of the bath, the activ­i­ty of burn­ing prod­ucts will depend on how the chim­ney pipe is cleaned.

If you do not clean the chim­ney, then the smoke will not be able to go out­side, which means it will accu­mu­late inside the room. In the future, this can pro­voke suf­fo­ca­tion. Over time, the walls will begin to col­lapse due to high tem­per­a­ture and chem­i­cal reac­tions. In addi­tion, there may be poor draft and a large amount of ash can lead to fire or fire.

When and how often to clean the chimney

The main signs that indi­cate that it’s time to clean the chim­ney:

  1. Poor draft from the fur­nace dur­ing com­bus­tion;
  2. Black smoke from the chim­ney;
  3. Flakes of soot fly from the chim­ney;
  4. Smoke enters the room;
  5. You have to open the low­er damper more strong­ly so that the fire­wood burns;
  6. Arbi­trary atten­u­a­tion of the flame;
  7. There was an unpleas­ant odor while burn­ing.
Black smoke is one of the signs that your chim­ney needs to be cleaned.


If the lay­er of plaque is thick enough, then dur­ing the fire­box it can catch fire from sparks. This may con­tribute to the destruc­tion of the chim­ney sys­tem.

If the design is of a sim­ple type, then the chim­ney can be cleaned inde­pen­dent­ly. Work should be car­ried out from the inside and from the out­side of the build­ing.

The stove chim­ney is cleaned reg­u­lar­ly every six months. How­ev­er, the pro­ce­dure can be car­ried out ear­li­er if char­ac­ter­is­tic signs of clog­ging are observed.

Cleaning methods

Depend­ing on the length of the chim­ney, the mate­r­i­al of the pipe, clean­ing can be done in sev­er­al ways: mechan­i­cal and chem­i­cal. There are also folk meth­ods that were used by our ances­tors. If you do the work using one of these meth­ods, then the sauna stove will become clogged much less often.

You can clean the pipe with your own hands, and if you have any ques­tions, seek help from spe­cial­ists.

In order to avoid prob­lems when clean­ing the smoke chan­nel, all meth­ods should be con­sid­ered, as well as addi­tion­al fac­tors should be tak­en into account: access to the pipe, clog­ging, the mate­r­i­al from which the chim­ney is made.

mechanical method

This is the eas­i­est and most pop­u­lar chim­ney clean­ing method. It is impor­tant to know how to clean the chan­nel so as not to dam­age the entire sys­tem.

When using this method, it is desir­able to assess how clogged and nar­rowed the lumen. To clean this way, you should pur­chase a spe­cial brush. Thanks to it, you can remove the result­ing lay­er of soot or soot. This brush has a flex­i­ble han­dle that allows you to thor­ough­ly clean the pipe. You can use a spe­cial flex­i­ble stick, which is screwed into each oth­er.

Brush for clean­ing

If the chim­ney is met­al, then you can not use a brush or brush with a met­al base, as this can dam­age the struc­ture. It is rec­om­mend­ed to use a poly­mer brush made of plas­tic.

When choos­ing a clean­ing tool, it is impor­tant that it match­es the size of the pipe. The device moves up and down.

Some mas­ters attach a load to the bot­tom of the brush, which they put on the cable. It is advis­able to take a cable that is designed for clean­ing sew­ers. It rolls well and does­n’t bend. This method is used when a con­ges­tion has formed and the ruff does not go fur­ther.

Ruff with a load


Before you start clean­ing, you should close all open­ings that lead into the house. This will pre­vent soot from get­ting inside. An open fire­place should be hung with a damp cloth. Mechan­i­cal clean­ing is rec­om­mend­ed when the soot lay­er is more than 1.5 mm thick. You can do the clean­ing on your own, with­out involv­ing oth­er spe­cial­ists.

chemical method

You can get rid of soot and soot with the help of chem­i­cals. Sub­stances destroy the formed deposits and do not harm health.

The most pop­u­lar means for remov­ing soot and soot are:

  • “Kominichek”;
  • “Chim­ney sweep”;
  • Anti-stain­ing chem­i­cal com­po­si­tion.

These are con­ve­nient and safe tools that allow you to clean the chim­ney with­out phys­i­cal effort and cost.

In con­struc­tion and hard­ware stores you can find a wide vari­ety of dif­fer­ent chim­ney clean­ers in the form of tablets, bri­quettes, logs. The prin­ci­ple of oper­a­tion is as fol­lows: the chem­i­cal decom­pos­es com­bus­tion prod­ucts, which pre­vents the for­ma­tion of soot. Under the influ­ence of high tem­per­a­ture, the gran­ules will melt and a sub­stance that dis­solves soot is released. This hap­pens by a cat­alyt­ic reac­tion — soot burns with­out the for­ma­tion of a flame.

Expo­sure to chem­i­cals

The tool is placed in the oven and burned with fire­wood. In case of severe clog­ging, sev­er­al packs can be used. Although these chem­i­cals are harm­less, at high con­cen­tra­tions they can be dan­ger­ous to the skin and mucous mem­branes. To avoid this, it is not nec­es­sary to remove the pro­tec­tive sheath. After clean­ing, ven­ti­late the room.

This method is not rec­om­mend­ed to be used more than twice a month. After the pro­ce­dure, heat trans­fer will increase and the con­sump­tion of sol­id fuel will decrease.

Folk ways


One of the meth­ods for clean­ing the chim­ney from accu­mu­lat­ed soot is the use of aspen fire­wood. Wood dif­fers from oth­er species in the absence of resins and low den­si­ty.

First you need to pre­pare fire­wood. They must be dry and clean. First, start a fire using birch or oth­er tra­di­tion­al wood. Then load aspen logs into the fire­box. The oven door and damper must be opened. Fire­wood should flare up strong­ly and the formed flame will pen­e­trate into the chim­ney. The soot will then ignite on the walls of the chim­ney. In the process of kin­dling, you can hear the hum of the stove, orange smoke above the chim­ney, and white flakes on the ground around the bath. These signs indi­cate that the process has reached a cer­tain phase.

Aspen wood is a good way to clean the chim­ney

If the soot block­age is strong, then you can break through it with boil­ing water. Before melt­ing the stove, you need to pour a few liters of hot water into the pipe from above. Steep boil­ing water soft­ens growths and pro­motes the destruc­tion of hot com­bus­tion prod­ucts. As a result, the plaque will fly out along with the smoke.

In order to pre­vent the for­ma­tion of soot, table salt should be used. Dur­ing the fire­box, a small amount of sodi­um chlo­ride should be poured into the fire­wood.

Effec­tive reme­dies for the accu­mu­la­tion of soot are pota­to peel­ings and naph­tha­lene.

Recommendations from experienced professionals

  • Before you start clean­ing, you need to cool the stove and clean the fire­box, as well as remove the dampers. Work should be car­ried out using pro­tec­tive equip­ment. Dur­ing the pro­ce­dure, harm­ful sub­stances can scat­ter and get on the mucous mem­branes.
  • It is desir­able to com­bine meth­ods for clean­ing the chim­ney for pre­ven­tive pur­pos­es.
  • Soot may appear again in a cleaned pipe over time, there­fore, for the pur­pos­es of pre­ven­tion, it is rec­om­mend­ed to per­form work at least 1–2 times every six months.
  • It is impos­si­ble to car­ry out work in rainy and windy weath­er. With a car­bon deposit thick­ness of more than 2 mm, major clean­ing will be required.
  • When clean­ing the chim­ney on the roof, a safe­ty device must be pre­pared.
  • It is rec­om­mend­ed to pre­vent exces­sive accu­mu­la­tion of soot and not to allow it at all, since clean­ing requires a lot of time and effort.
  • It is unde­sir­able to use resinous rocks for the fire­box.
  • If the clog­ging is severe, then two meth­ods can be com­bined: first clean it using chem­i­cals, and then mechan­i­cal­ly.
  • When using chem­i­cals, read the instruc­tions. Some of them can be applied in dif­fer­ent ways, so it is impor­tant to know all the nuances: whether or not to remove the wrap­per, whether it is nec­es­sary to ven­ti­late the room, etc.
  • If objects with a dis­placed cen­ter of grav­i­ty are used dur­ing mechan­i­cal clean­ing, then there is a high prob­a­bil­i­ty that they will get stuck in the pipe. To remove it, you will need to com­plete­ly dis­as­sem­ble the chim­ney.

These tips are use­ful to know not only for begin­ners, but also for expe­ri­enced crafts­men.
