This study was made in an effort to explain the development by dry cleaning of brown stains on silk and wool garments soiled with salad oils made from vegetable oils. The results indicate that age, light, and oxygen alone are negligible factors - the chief contributing cause being heat in the presence of air. This condition is brought about by hot pressing before cleaning or drying in a tumbler in a dry cleaning plant. Corn oil is particularly troublesome, due apparently to the larger percentage of esters of unsaturated fatty acids.
