Dust and debris may not be as noticeable on the subtler shades of stone fireplaces when compared to brick, but regular cleaning is essential. The microscopic pores on natural stone surfaces like granite, limestone, or slate can accumulate dust, dirt, soot, and creosote. Creosote, a dark brown substance formed from the by-products of combustion (such as smoke or vapor), can increase the risk of chimney fires. Regularly removing these build-ups, a task that is both simple and cost-effective, is crucial for preserving the aesthetic appeal, functionality, and safety of your fireplace.
