Can Fiberglass Planter Boxes be pressure-washed?

Fiberglass planter boxes are a popular choice for outdoor gardening due to their durability and lightweight design. However, many gardeners wonder if these planters can be pressure-washed to remove dirt, stains, or algae buildup. The answer is yes, but with caution. Fiberglass is a strong material, but excessive pressure or using a high-pressure setting can damage the surface or cause cracks. To safely clean your fiberglass planter boxes, use a low-pressure setting and hold the nozzle at least 12 inches away from the surface. Avoid harsh chemicals and opt for mild soap or a specialized cleaner for fiberglass. Regular maintenance, such as wiping down the planters with a soft cloth, can also help keep them looking new. By following these tips, you can ensure your fiberglass planter boxes remain in excellent condition for years to come.
