Effortlessly Revive Potted Plants with WD-40 and Kitchen Staples

Calcium buildup on the outside of potted plants can be removed using WD-40. First, clean the planter of dirt and debris. Shake the can of WD-40 and spray a light coat onto the affected areas. Let it sit for a few minutes, then scrub with a soft cloth or brush. Rinse with water to remove residue. To prevent future buildup, use filtered or rainwater for watering and regularly clean the planters.
