Here's how the people at my club taught me to wash a lamé:
1.Fill a pail of water.
2.Put in a drop of detergent.
3.Soak the lamé.
4.Remove the lamé after a few minutes.
5.Dry it with a cloth and blow it with a fan if you want to make the drying process quicker(do not hang it in the sun).
6.Hang it up somewhere for the remianing moisture to dry up.
This should be the correct method.Armorers,correct me if I'm wrong
