If you’re looking to clean a limestone fireplace, there are a few things you’ll need. The first is a bucket, as the ashes will be very dirty. Second is a cloth or paper towel, as the ash will be very thick and difficult to clean with just your hands. Third is a vacuum cleaner with the hose attachment, as the ash will be very dirty and clogged up. Finally, you’ll need some water and some soap. Pour enough water into the bucket to cover the ashes and then add enough soap to make sure it’s fully mixed in. Turn on the vacuum cleaner and wait until it starts sucking up all of the dirt and ash before turning it off. Be sure to let it run for a few minutes so that all of the soap has been absorbed into the ashes.
