Dry cleaning is a PITA for me. The closest place is 30 kilometers from my house and is open only in the mornings. I have four pairs of dress wool pants (two heavy wool and two light, summer, wool). They all say on them "dry clean only". I also have a washer-dryer that has a wool cycle and a bottle of "Woolite". Is there any reason that they really have to be dry cleaned? What will happen if I put them in the washer?
