Common

1 Gently wipe the leaves with a soft, damp cloth using distilled or rainwater to remove the crusty mineral buildup without damaging the plant's farina coating.

2 Switch to using distilled water, rainwater, or filtered water for future watering to prevent new calcium and magnesium deposits from forming.

3 Monitor soil moisture levels to ensure you are not overwatering, which can exacerbate mineral accumulation in the substrate.

Common
