Before your first fire of the season, it’s important to make sure your firebox is clean of ashes.
According to the DIY Network, you’ll know it’s time to clear the ashes when they reach the grate. You can do this by simply sweeping or vacuuming the ashes out.
However, before you dispose of them, make sure the ashes you clean out are cold—some coals can stay hot for up to three days. It’s recommended that you don’t clean until it sparkles, though. About an inch of ash in the fireplace actually will make it easier for you to light that next fire and keep it burning.
When cleaning your ashes, safety first! Wear a mask and eye protectors to make sure the ashes don’t harm you in any way.
