No need for a dry cleaner to iron out wrinkles. Just by hanging it up, sometimes, the weight of the fabric will work the wrinkle out. If not, use a steamer; hang it up in the bathroom while taking a shower; or use the iron, on wool setting, but place a cloth underneath to act as a barrier between the apron and the iron. The heat of the iron may scorch the wool, so make sure to use a cloth and, preferably, one that is sightly damp.

I seldom have to iron or steam my heavy/medium weight wool kilts. I just hang it up and let nature do its thing.
