I started pressing kilts with a regular clothing iron. You have to use a pressing cloth between the iron and the kilt to prevent material "sheen". Since then, I have found that a professional pressing iron/steam generator is far superior.

It supplies "dry" steam and pretty darn hot at that. I often feel the burn if I have my hand holding a pressing ham and I am not careful to direct the steam away from my hand. The "dry" steam goes right thru the kilt and ironing board so the kilt doesn't get as wet after pressing compared to the regular iron. You don't need a pressing cloth if you have a teflon shoe attached to the pressing iron too. It is a lot fast to press a kilt and the pleats are much sharper, I can almost cut myself with those pleats but won't ship them to the unsuspecting kilt wearer as it may cause... ok, not that sharp but better than the regular iron.

Cheers,
