As an 18th century military reenactor, our kilts go through a lot of &*%$ I have had mud, gunpowder residue, soup (one of my lads spilled soup on me one evening!!), etc. on my kilts....these are NOT my Newsome kilt or the box pleats that my wife has made, they are for dress. But, as others have said, let the dirt or whatever dry, brush and then I handwash. No problems!
