Natural fabrics support more fungal growth than synthetic fabrics. Synthetics, once contaminated, are easier to clean. After almost a year of research, our study found that there is a difference in mold removal effectiveness between various cleaning procedures. The study evaluated the cleaning effectiveness of four fabrics: cotton, wool, polyester and silk.  We used four cleaning methods: perchloroethylene, hydrocarbon, washing and washing with chlorine bleach. The cleaning processes were designed to be baseline processes with detergent added to the dry cleaning procedure and laundering with Light micrograph (200x) of polyester fabric after incubation showing limited growth. detergent with and without chlorine bleach. Laundering with the addition of chlorine bleach was evaluated because of the known effect of bleach on mold. Two types of common fungi, stachybotrys charterum and aspergillus versicolor, were used in the study. The fabrics were treated with spores, allowed to incubate, cleaned and reevaluated.
