There is then the necessity of reconsidering employment of oxidizing and reducing agents.

Issues on environmental conservation and trends favoring fine fabric would result in dropping rough means of cleaning such as those using chlorine.

Safe and thoroughly calculated wet laundering would be required. Usage of harmless and effective oxidizing and reducing agents would become necessary for stains that cannot be removed by detergents. Practical training on bleaching by oxidation and reduction as a new cleaning technology should be carried out, as well as development of further bleaching technology which does not cause degradation of materials.

Oxidizing and reducing agents such as chlorinated isocyanuric acid and aminoimino-methanesulfinic acid should also be brought into view.

Practical trials are anticipated.
