I have had a 3100 PSI pressure washer for about 7 or 8 years and used it on occasion, not enough yet to justify its $300 cost back then. Anyway I have used it to clean outdoor things, the house siding that does not get sun, a car wash a couple of times and of course my motorized lawn and garden things.
When we were in Japan, about a year before we came home, LOML found a Adirondack chair that was in a "kit" and wanted it. We got it - it was basically some kind of fir or cypress. I have always accepted that fact that outdoor wood, not painted would age to "wood grey", and that one did. (We bought it back with us of course).
LOML asked me to pressure wash the chairs and porch swing on our back porch to get years of dust out, and I decided to wash the grey wood adirondack and WOW, it cleaned like it was more or less grey from dirt than aging wood. It brought back the natural wood look of its original color. I didn't know that pressure washing would do that to old wood. Maybe it was taking a layer of wood cells off.
For you experienced guys, which was it? Cleaning out the dirt, or stripping of outer grey cells off?
