Fabrics Suitable for Dry Cleaning
4. Although all cleaning agents may be used on practically all fabrics without injuring them, dry cleaning is best suited to silk, rayon of all types, wool, and part-wool materials.
Velvet may be dry cleaned, but it requires a longer time to dry.
Plush and fur may be cleaned by immersion or by brushing and spotting.
Cotton and linens may be dry cleaned if water is likely to affect their appearance dangerously, but soap-and-water cleaning is more simple for such fabrics and gives a freshness that is desirable.
Cloth shoes and slippers, parasols, or articles not made entirely of fabric should not be dry cleaned by immersion. They may be sponged to restore them and to remove stains.
