Sand and Treat Deck Railing?
1. I would use the 2 and 1 combo. Saves time and money. In my experience, the 2 and 1 stain/sealer have done a solid job.
2. They do have special wood cleaners. A bucket and brush would do just fine. Save the money on the power washer.
3. In my experience, the spraying on stain/sealer doesn't produce results like a brush. Unless you go out and buy an expensive sprayer. The brush will produce a nice even finish. Don't buy a cheap brush...you may regret it.
Remember, it is all about the prep work. Never take short cuts on prep work. It makes a huge difference.
I have a cheap home depot stockade fence that I prepped and painted about four years ago. It is still holding up very well.
