What do you have to do?
- Sweep your deck or patio thoroughly. Try to get your tiles as leaf and filth-free as possible.
- Fill a bucket with equal parts vinegar and water (for example, a liter of vinegar and a liter of water).
- Spread the vinegar water across the tiles and scrub it in with a broom. Let the vinegar water sit and don’t rinse it off. After a few weeks you’ll notice the green buildup disappearing.
