What are the risks of using harsh detergents on sealed stone outdoor garbage bins?

Using harsh detergents or acidic cleaners on sealed stone outdoor garbage bins poses significant risks. While the sealant provides a protective layer, aggressive chemicals can compromise it. The primary danger is chemical etching, where acidic or alkaline substances permanently dull and roughen the stone's surface, creating visible stains and marks. This etching not only looks bad but also makes the stone more porous and prone to future staining.

Furthermore, harsh cleaners degrade the protective sealant itself. Once this barrier breaks down, moisture, oils, and dirt penetrate the stone, leading to deep-set stains, potential mold growth, and even freeze-thaw damage in colder climates. Many strong cleaners also cause discoloration or fading, stripping away the stone's natural color. To maintain your bins, use pH-neutral, stone-specific cleaners, warm water with a mild dish soap, or dedicated stone soaps. Regular rinsing and prompt spill cleanup are the best practices for preserving both the sealant and the stone's beauty and longevity.
