This study is an outgrowth of the controversy over the use of hot water versus cold water for effective detergency. The study reported here was undertaken to compare a detergent used in hot water with a detergent used in cold water as bacteriostatic agents on cotton. The effect of four variables in the removal of Staphylococcus aureus and Escherichia coli bacteria from cotton fabric specimens during washing was investigated.

More specifically, the objectives were to determine: (1) the percentage of bacteria removed in each stage of the multiple-cycle washing process and that which remained on the fabric after laundering; (2) any differences between hot water washing with a detergent and cold water washing with a cold water detergent on the removal of bacteria from cotton fabric; (2) any differences between hot and cold water washing without detergent on bacterial removal; (4) the effect of washing with detergent compared to washing without detergent for both hot and cold water; (5) any differences in residual bacterial content on fabrics washed immediately after inoculation compared with those washed 24 hours after inoculation and subsequent incubation; (6) any differences in the survival of two bacteria, one a Gram positive and the other a Gram negative, throughout the washing process.
