You can spot clean little mishaps with just a bit of water and some dabbing, you can carefully clean one with a bit of baby shampoo and cool to tepid water in your bathtub too, lay it flat and walk on it carefully to clean the wool, rinse the same way and then press the water out between towels on the floor being mindful of the pleats. Another option is basting the pleats and taking it to a knowledgeable dry cleaner who can properly clean and press a kilt.
Storage wise I use the two hanger method, fold kilt in half, use two clip style hangers (I get mine cheap at IKEA) and clip them to the waistline on both sides and fold both halves together and hang up.
