How to clean the glass in a fireplace from fouling?

Anyone with a fireplace in their home knows, of course, that it requires proper maintenance and regular procedures that affect its proper operation. If you do not take this into account, there will definitely come a time when the beautiful view of the dancing fire in the fireplace stove will not be available to you, due to a significant decrease in the transparency of the glass. Everyone loves to watch the flame flickering in the fireplace, so in today’s article we will give an answer to the question of how to quickly and effectively clean the glass in the fireplace from the soot.

Causes of impurities and how to eliminate them

Before you begin to remove the buildup from the glass doors of your fireplace or stove, you should know the causes of the buildup and how to remedy it.

Smoke on the glass is caused by wood and fuel combustion, which is a perfectly natural process, but there may be other, technical “culprits” of soot and soot trails. What contributes to it? If the room is heated:

  • Firewood. especially logs from softwood trees, the tar present in them contributes to the accumulation of a layer of soot and smoke on the glass. The cause can also be partial combustion of wood, lack of special openings for oxygen penetration, clogging of the gas exhaust pipe;
  • Gas fuel. the formation of a large amount of plaque and soot appears due to a violation of the proportions of gas and air, and indicates that the hearth is clogged burners, nozzles are in the wrong position or there is any damage in the work of the tank-controller;
  • Propane. the most common cause of soot on the glass door in closed fireplaces is low-quality propane. Fouling can also form as a result of malfunctioning of the tank, clogged burners. If you clean them and replace the fuel with a cleaner one, the amount of fouling will decrease.

If the glass has to be cleaned from the plaque with soot about 1 time in 3-4 weeks, and there are not too many, it indicates the full operation of the fireplace or furnace.

But if in 1-2 weeks after cleaning, from the protective door again need to remove dirt, and in large quantities, it signals that there are malfunctions in the functioning of the heating system.

Correcting the existing problems will help reduce the amount of soot and grime deposited on the glass door.

In addition, there are several common methods, with the help of which you can quickly and effectively clean existing dirt. How you use cleaning agents (household, chemical or folk) depends on the type, smoke level and budget.

A clean glass fireplace is the responsibility of a proper system of air supply to the furnace. In BRUNNER fireplaces, the air that enters the furnace creates an invisible shield in front of the glass, blowing clean air and preventing soot and soot from settling on the glass.

In many stoves and fireplaces the air is supplied through the ashtray and grate, and during the operation of the fireplace there comes a time when the ash closes the air supply to the furnace The furnace is switched to a sub-optimal combustion mode, which is eventually visible on the glass.

Soot on the glass in the stove. Why does it happen and how do you fight it??

Soot. is unburned fuel. It appears when there is insufficient draught in the chimney or the wood burning temperature is too low. Universal protection against soot formation. Clean glass system. It will solve all the problems. But even if your stove does not have this system. don’t worry. Avoiding the following causes of soot will keep the glass clean, allowing you to enjoy a lively fire.

The reason you use newspapers to kindle the stove

And you do not want to do that. The composition of the ink used in printing is such that when burned, it instantly turns into a very “clingy” soot that settles on the glass. So you should only use clean paper to kindle the fireplace stove. But perhaps the best option is a gas burner.

How to Clean Fireplace Glass. Removing Burnt On Soot From Glass

Watch our video “How to kindle your sauna stove without smoke”. This method is also suitable for stoves.

Solution: clean the glass with a special cleaner and never use newspapers for burning.

Bad draft = soot on the stove glass, and even some smoke. There may be several reasons for draft deficiency: 1) the furnace and chimney have not yet warmed up; 2) the height of the chimney is not sufficient; 3) there is no air intake ventilation.

The solution to the first problem is simple. make sure that during firing up all the chimney flaps are open. If there is still not enough draught, open the door slightly. Also, after firing up the stove for 20-30 minutes, do not put it into continuous burning mode.

The second problem can be solved by increasing the height of the chimney. Don’t know until when? Call us and we will tell you! Tel. 8 (812) 605-85-05.

In the third case, if the house did not originally have intake and exhaust ventilation, there is only one solution. to periodically open the window to let in fresh air.

Cause Hasty setting of the oven to continuous burning

We partially covered this reason in the previous point. If you put the stove into long burning mode before it and the chimney are warmed up, there will be soot on the glass. We also do not recommend using this mode often. Read why in this article: https://nkamin.ru/blog/pechi-dlya-doma/chto-takoe-rezhim-dlitelnogo-goreniya-fakty-domysly-i-zdravyy-smysl

Solution: reduce the combustion air supply only after 20-30 minutes after firing up the stove.

The more “wet” the wood you use, the more likely the soot is to form. Use only dry wood with relative humidity of less than 20%. It’s about 1.5 to 2 years of drying in a ventilated woodstove.

The reason The log touches the glass

Not an obvious reason, but one which also causes soot on the oven glass. The point is that the temperature in the furnace is always higher than on the surface of the glass. This will cause the logs touching the glass to “cool down” and will make the combustion worse. Because of that there will be soot.

Solution: make sure the logs do not touch the glass and put them as deep into the firebox as possible.

Methods and tools for cleaning fireplace glass from soot

If your fireplace is operating properly, regardless of the fuel used, there should be no soot buildup on the doors, especially in large quantities. If you have to look through a dirty glass systematically, however, look for the cause:

  • If your hearth is gas-fired, fouling and soot indicate clogged burners or improperly positioned jets. These factors result in an incorrect air to gas ratio, affecting the condition of the inside of the firebox;
  • Propane-fueled furnaces are prone to fouling more often than gas-fueled hearths. And the most common causes are poor-quality fuel, improper gas to air ratio, clogged burners, malfunctioning tank regulator;
  • Wood burning stoves are the most prone to sooting. Reasons: use of coniferous wood, incomplete combustion of fuel, no holes for air intake, dirty exhaust pipe.

If you have to clean the glass door more than once in two weeks, we recommend that you look for the cause. The formation of soot is characteristic of closed fireplaces, so contamination can appear even if there are no problems in the work of the furnace.

Basic cleaning methods
