I'm not sure why I didn't think of this before, but if you had access to a steam dryer how would that change drying times? Still 20min on a dry item? I believe the steam runs hotter than a non steam dryer. Would steam be harmful as it keeps items damp?
I also have a rack to put in my dryer for items that can't be tumbled. Do you think I could treat books or puzzles in that manner? Maybe my fabric storage cubes? Last thing I need is a fire! Just processing thoughts.
