How to clean patio?

Anthony, have you considered a pressure wash? You can rent one for a weekend, OR get the attachment that works on your hose. The attachment is not quite as harsh or fast, but works well and you can get them at most home improvement stores now.

pressure washing a concrete slab, patio, driveway, etc is the best way to clean it
