soaking in 50/50 detergent/water isn't a drying solution it's a solution for spalted (punky) wood.The theory being that the detergent breaks the cellular wall barrier allowing the flaccid, denatured cells to "plump up" and allow turning without the attendant problems of spalted wood.
Boiling rough-turned objects is a drying technique. The theory being that boiling also results in the boiling off of cellular moisture which results in a more stable blank when finished turned.
neither are guaranteed.
