Surface cleaner on decks
I have tried it twice, with mixed results. If you have experience with surface cleaners on concrete, you know about overlap, the correct speed, chem. use, etc.
Wood is not much different. Maybe it requires a little more TLC to prevent damage. It will make the job faster and easier with good results. The corners, edges, and other hard to reach areas will need to be cut it; just like on concrete. No big deal.
The only problme I had was on one dock that was just a little wider than by cleaner, so I had to make two passes, and the overlap was quite obvious. That is the only drawback. If you can avoid overlap, it is a great way to clean decks.
