The study into the effects of conservation wet cleaning on standard, soiled wool fabric was done in order to determine the most gentle, yet efficient wet-cleaning method. The results were obtained by analysing standard soiled test fabrics from a previous series of wet cleaning tests. Comparisons were made between anionic and non-ionic detergents used in different concentrations and between different washing methods. The analyses were carried out to show changes in surface characteristics, dimensions, soil removal, tensile strength, and weight. The results demonstrated that the wool fabric shrank with each treatment. The shrinkage was more severe when the soil removal was more effective. The cleanest results were obtained with the warmest wash bath of 30°C for both detergents. This washing method was also the most damaging to the fibres. Based on the results, the use of a non-ionic detergent is recommended for the conservation wet cleaning of wool. -- CAL
