Don't ever use chlorine bleach to clean wood.
It is highly alkaline and will raise the pH of the wood to a point where you cannot rinse it out. The higher pH will cause any stain or paint to fail prematurely, leaving you with a huge mess. There are cleaners available that will clean with an oxygenated bleach (instead of chlorinated) and will not ruin the wood. Wood ReNew from Perma-Chink is the best I've ever used. If someone has used bleach on your wood, you can reduce the pH and make the wood suitable for staining or painting again by applying oxalic acid to the wood.
Thanks, but I'll stick to materials that are designed with all of the characteristics necessary for cleaning and protecting wood construction. A firm that manufactures and promotes (by their own website) mostly for everything except exterior wood and is interested in selling huge quantities to a store that caters to do-it-yourselfers tells me one thing. They are primarily concerned with promotion, volume, and frequency of use and application. The only advantage that I can see is that you can go to any store and pick the material up. The real question is: Who benefits from that?
I used their cleaner on my deck a few years back, then oiled it again with the same product I ...»
John, that is a sweet timber frame porch!!!
Like I said earlier: There are a few good quality oil-based & solvent-based products available. You just won't find them at a big-box store because, at their price level, homeowners shopping in those stores would never purchase them and it takes a professional to correctly prep the wood and apply them. The expense of maintenance is always in the labor, never in the materials. So, if you use the right materials, you can easily cut the ongoing expense by 75% as compared to the cost of cleaning the surface and reapplying the mass-manufactured stuff every 2 or 3 years.
Now, here's a timberframe porch I built at the Ritz-Carlton Lodge in Georgia.
