How to clean lichen growth from stone outdoor ottomans?

Lichen growth on stone outdoor ottomans can be unsightly and difficult to remove, but with the right approach, you can restore your furniture's appearance safely. Here’s a step-by-step guide:

1. Prepare a Cleaning Solution: Mix equal parts water and white vinegar or use a mild dish soap solution. Avoid harsh chemicals that may damage the stone.

2. Scrub Gently: Use a soft-bristle brush or sponge to scrub the lichen-covered areas. Apply the solution and let it sit for 10-15 minutes to loosen the growth.

3. Rinse Thoroughly: Rinse the ottoman with clean water, ensuring no residue remains. A garden hose works well for outdoor cleaning.

4. Prevent Future Growth: Apply a stone sealer to protect the surface and reduce moisture retention, which encourages lichen.

5. Natural Alternatives: For stubborn lichen, baking soda paste or oxygen bleach can be effective without harming the stone.

Regular maintenance and prompt cleaning will keep your stone ottomans looking pristine for years.
