Ryobi pressure washer surface cleaner vs old deck.

I don't usually review products like this but I think this is amazing. At no point did it damage the wood in anyway but it also cleaned it better than just using a regular nozzle which if you've ever cleaned an old deck you know results in damage usually. It's also significantly faster than using a regular nozzle and more uniform results.
