Kind Code:
A1
Abstract:
An object of interest, which is to be cleaned, is pretreated with an oxygen bleach (S2), and then the object is partially patched with a cotton-made cloth (S3). The whole body of the object of interest is wrapped with a cotton-made cloth (S4), is then placed in a net (S5), and is then allowed to leave for a certain period of time (S6). The conditions for a washing machine are set (S7), then the object of interest is put in a washing tub (S8), and detergents to be used in the individual steps are set in the washing machine (S9). Subsequently, a washing step (S10), an intermediate dehydration step (S11), a rinsing step (S12), a final dehydration step (S13) and a drying step (S14) are carried out. In the washing step, a liquid soap, SOFSIL (registered tradename), FAMITON (registered tradename), alum and water are put into the washing tub. In the rinsing step, SOFSIL (registered tradename), FAMITON (registered tradename) and water are put into the washing tub. In this manner, in a cleaning method for washing an object of interest which is made from a natural material with water, dirts can be removed satisfactorily from the object and the occurrence of deterioration in quality of the object, such as shrinkage, change in texture and color migration, can be prevented.
