Excerpt from: "The ABC's of Conservation"
Vacuuming textiles through a screen prevents damage to delicate fabric and trims. Keep the screen firmly against the textile while cleaning.
Make fold-over polyester screens in several sizes for both vacuuming and wet cleaning.
The edges of the screen are bound with white cotton fabric, which is also used for ties, on three sides. These screens are also used for wet cleaning.
The baking soda has been gently shaken from the costume. It was then placed between a folded and tied screen, and vacuumed thoroughly.
