Why Is My Patio Turning Green?

Your patio is a peaceful retreat, perfect for enjoying the beauty of your garden, relaxing by the pool, and spending quality time with friends and family during the warmer months. It also plays an important role in enhancing your home’s overall aesthetic. However, a greenish tint can quickly detract from its charm. What causes this, and how can you fix it?


This greenish hue typically appears on wood that’s left unprotected from the elements. Moss or lichen tends to grow in damp conditions or on cloudy days, especially during the winter months. In addition to being unsightly, these moss deposits can make the surface slippery, increasing the risk of falls. If not cleaned properly, they can also cause long-term damage by promoting water infiltration.


The good news is that there’s no need to panic — this problem is easy to fix. An Exterior Wood Cleaner & Brightener will easily remove the green moss. Simply prepare the cleaning solution, brush the affected patio areas, and rinse thoroughly with a garden hose. There’s no need for a pressure washer; a good scrubbing followed by rinsing will do the trick. Avoid using bleach, as it’s harmful to the environment, and opt for Eco-friendly products designed for this purpose.


To prevent the problem from coming back, it’s recommended to treat your patio regularly with a quality oil. After the snow has melted and in the fall, clean your patio with a solution of water and Black Soap, then rinse it off with a garden hose.
