When to dispose of burnt ashes?

Proper disposal of fireplace ash is a serious matter as one of the main causes of home fires is improperly disposed of hot wood ash. When the weather is cold outside, warm, cozy fires can be delightful. However, once it’s cleared, many people simply scoop up their ashes and dump them in their plastic waste container. However, it can store enough heat to ignite.

So never store or dispose of hot ashes in a flammable plastic waste container. This one simple action is a leading cause of home fires and has turned many memories of a delightful, cozy evening fire into a disaster. After a few hours in the plastic waste container, the ash has ignited the dumpster and suddenly the home can be on fire.

Different woods like softwood or hardwood burn differently


In addition, the type of wood burned determines the amount of wood ash produced. Simply put, softwoods like fir, spruce or birch tend to weigh less. However, they produce more ash than hardwood varieties such as beech, maple, or ash. In any case, when the fire burns down, a lot of ash remains in the stove or fireplace. That is why wood stoves and fireplaces should be cleaned regularly.

One of the biggest mistakes people make is removing the ashes from the fireplace every time a fire is lit. A thin layer of ash at the bottom of the fireplace helps insulate the fire, making it burn hotter and longer. It is therefore best to leave about an inch/2,5cm of ash. So consider clearing away the ash once it has piled up past this point. When it reaches the bottom of your grate, ash removal is overdue.

Before you start the cleaning process

Regularly dispose of ashes from a firebox of wood stove with an ash shovel

As already mentioned, a layer of ash can protect the bottom of your firebox during the heating season. This is because the ash is a buffer between actively burning wood. The time to remove the ash depends on how often a fire burns in your wood stove or fireplace. If this is your primary heat source, you should inspect and clean the ash container every week. This should leave a 1 inch/2.5 cm thick layer. So wait until the fire has gone out and the ash has cooled down enough. For people who heat with wood, the best time to do so is in the morning, before lighting or re-lighting the first fire of the day. Use a small metal ash shovel to scoop the leftovers into a metal bucket.

In addition, hot embers can hide in a fireplace ash bed after the fire appears to have burned out. It is therefore important to ensure that the fire has cooled completely before disposing of the ashes. It’s also a good idea to wait at least 24 hours after the fire is out before you start cleaning up. It is best to treat your fireplace ash as if it could still be hot. If you plan to store the ashes in your home, you should cover the bucket with a tight-fitting metal lid, or place it in the garage or a well-ventilated area. If combustion still takes place, the ash can release carbon dioxide, which is a real hazard.

Boil your recycled ash in water for about 30 minutes, then allow them to settle to the bottom of the pan to create lye. This is the common name for sodium hydroxide and is a key ingredient in soap making. When the ash is boiled, the lye forms accordingly on the water, which you can skim off afterwards. Hardwood ash is best for making lye because softwood ash is too resinous and produces a lye that does not mix well with the fat used in soap making.
