It's best to spot clean your kilt with a damp cloth.
However, if you feel it needs a machine wash, we recommend that you do so on a cold, delicate cycle. Make sure the belts/buckles are done up so they don't catch on the drum.
Wash the item alone.
Hang it to dry or lay it flat to dry. NEVER put a kilt in the dryer.
Make sure the kilt is 100% dry before storing away.
