What are the risks of using pressure washers on porous stone outdoor planters?
Using pressure washers on porous stone outdoor planters can pose several risks. The high-pressure water can erode the stone's surface, leading to cracks, chips, or even structural weakening over time. Additionally, porous stones like limestone or sandstone absorb water easily, which may cause internal damage or promote mold growth if not dried properly. The forceful spray can also strip away protective sealants, leaving the stone vulnerable to stains and weathering. To clean porous stone planters safely, opt for gentle methods like soft brushes and mild soap instead of high-pressure tools. Proper care ensures longevity and preserves the natural beauty of your outdoor planters.
