Purists might object, but these things are made of "resin," not wood. They are heavy. They have been outdoors for over a year and had accumulated mildew and dirt, so I decided to give them a bleach spray bath last weekend. It worked like magic.
I asked Mrs. BD whether she wanted me to put them inside someplace for the winter and she told me not to bother. "They're resin." I said "You mean plastic." I never realized it. I am happy to know that a lifetime of scraping, painting, and replacing rotting Adirondack chairs is over.
