Pool decks can serve as a breeding ground for a variety of harmful organisms like algae, fungus, and pests because of the moisture they contain. They tend to also accrue grime, dirt, sand, and pool chemicals making it displeasing and not something you’d want brought back into your home. Cleaning your pool deck and patio furniture on a regular basis prevents the spread of these contaminants leaving a beautiful looking patio ready for its next family gathering.
