I use Woolite or a gentle washing liquid, COLD water and the "Gentle" fabric setting on my washer. There is minimal agitation. I stop if after the rinse cycle, but before the spin (even though the spin on this setting is quite minimal). In other words the kilt is "sopping wet" when I remove it from the washer.

I run a heavy dowel (broom handle) through all of the belt loops, pull it tight along the dowel and then suspend the length of dowel from the rafters in my cellar or out doors, to "drip dry." I take a few minutes to stretch and smooth the pleats back into shape and go about my business. As all my kilts (so far) are synthetic fabrics or synthetic blends, they dry over night in the cellar. If you hang them outdoors, you may want to find a shady spot, so the sun won't fade any of the colors.

UKs have no belt loop at one end, so that end does droop, but a clip can be attached to hold it up level with the rest of the kilt's waist.

On kils with few or no belt loops, it's more of a challange. The heavy weight of the sodden kilt (especially if it is wool) will usually pull out from most skirt hanger clips. So, some construction of a dowel, to which you've attached a few heavy-duty clips (available at Home Depot or most good hardware stores). You could even use a low cealing in the basement and attach heavy-duty clips along an overhead beam, to which you could simply clip the wet kilt when it comes out of the wash and not bother with running a dowel through belt loops. (This scenario requires that you don't care if you basement floor gets wet, however.)

They look great, it costs nothing but a few minutes and you don't have to plan your wardrobe on the cleaner's schedule.

I can't see why wool wouldn't work the same way.
